Oral Bioavailability: Gabapentin bioavailability is not dose proportional; i.e., as dose is increased, bioavailability decreases. Bioavailability of gabapentin is approximately 60%, 47%, 34%, 33%, and 27% following 900, 1200, 2400, 3600, and 4800 mg/day given in 3 divided
Mechanism of Action The mechanism by which gabapentin exerts its analgesic action is unknown, but in animal models of analgesia, gabapentin prevents allodynia (pain-related behavior in response to a normally innocuous stimulus) and hyperalgesia (exaggerated response to painful stimuli). In particular, gabapentin prevents pain-related responses in several models of neuropathic pain in rats or mice (e.g., spinal nerve ligation models, streptozocin-induced diabetes model, spinal cord injury model, acute herpes zoster infection model). Gabapentin also decreases pain-related responses after peripheral inflammation (carrageenan footpad test, late phase of formalin test). Gabapentin did not alter immediate pain-related behaviors (rat tail flick test, formalin footpad acute phase, acetic acid abdominal constriction test, footpad heat irradiation test). The relevance of these models to human pain is not known.

神经系统英语作文The Nervous System: The Command Center of the Human BodyThe nervous system, often referred to as the command center of the human body, is a complex network of specialized cells that controls and coordinates all our bodily functions. This intricate system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).The CNS consists of the brain and spinal cord. The brain is the master controller, responsible for processing information, making decisions, and initiating responses. It is also involved in memory, emotions, and consciousness. The spinal cord, on the other hand, serves as a pathway for signals to travel between the brain and the rest of the body.The PNS consists of nerves that branch out from the spinal cord to connect with various organs and tissues. These nerves are further divided into the somatic nervous system, which controls voluntary movements and sensations, and the autonomic nervous system, which regulates involuntary functions such as heart rate, blood pressure, and digestion.The nervous system works in close collaboration with other body systems, such as the endocrine system, to maintain homeostasis, the state of balance within the body. It is a highly adaptable and resilient system, capable of regenerating and reorganizing itself to some extent after injury.In conclusion, the nervous system is a vital part of the human body, essential for survival and the performance of daily activities. Its complexity and sophistication are a testament to the remarkable design of the human body.。

神经科学揭示大脑运作奥秘的英语作文
神经科学揭示大脑运作奥秘的英语作文Title: Unraveling the Mysteries of Brain Function: Insights from NeuroscienceIn the intricate tapestry of life's wonders, the human brain stands as a beacon of complexity and elegance, its workings shrouded in mystery for centuries. Neuroscience, the scientific discipline dedicated to unraveling these mysteries, has emerged as a beacon of light, illuminating the intricate pathways that govern our thoughts, emotions, and behaviors.IntroductionThe human brain, a marvel of evolution, comprises billions of interconnected neurons, each a tiny universe of electrochemical activity. It is through these intricate connections that the brain processes information, stores memories, and generates consciousness. Neuroscience, fueled by advances in technology and research methodologies, has made remarkable strides in understanding this remarkable organ.Uncovering the BasicsAt its core, neuroscience explores how the brain processes information. It delves into the neural circuits that underlie perception, cognition, emotion, and motor control. The discovery of neurotransmitters, such as serotonin and dopamine, has revolutionized our understanding of mood regulation and addiction. Functional neuroimaging techniques, like fMRI (functional magnetic resonance imaging), have enabled researchers to visualize brain activity in real-time, revealing how different regions of the brain light up in response to various stimuli.Exploring ConsciousnessOne of the most elusive aspects of neuroscience is the study of consciousness. How does the physical brain give rise to the subjective experience of being? Researchers are exploring this question through studies on sleep, dreams, and altered states of consciousness. Theories of consciousness, ranging from the global workspace theory to integrated information theory, aim to provide a framework for understanding this fundamental aspect of human experience.Memory and LearningMemory, the cornerstone of our identity, is another major focus of neuroscience. From short-term to long-term memory, researchers are uncovering the molecular and cellular mechanisms that underlie memory formation and retrieval. The Hebbian theory of synaptic plasticity and the role of the hippocampus in memory consolidation have shed light on how our brains encode and store information. Furthermore, studies on neuroplasticity have shown that the brain is capable of rewiring itself, even in adulthood, offering hope for treating conditions like Alzheimer's disease.Future ProspectsAs neuroscience continues to evolve, the implications for society are profound. From enhancing cognitive abilities and treating neurological disorders to developing ethical frameworks for emerging technologies like brain-computer interfaces, neuroscience promises to reshape our understanding of the human condition. The journey ahead is fraught with challenges, but the potential rewards are immeasurable—a deeper understanding of ourselves and the universe we inhabit.Translation:标题:揭示大脑功能奥秘:神经科学的洞察在生命奇迹的复杂织锦中,人类大脑作为复杂与优雅的灯塔,其运作方式数百年来一直笼罩在神秘之中。
神经的英语知识点总结
神经的英语知识点总结The nervous system is a complex and intricate network of cells, tissues, and organs that allow the body to communicate and coordinate its actions. It is responsible for receiving and transmitting information, controlling movement, regulating bodily functions, and mediating the body's response to external and internal stimuli.Structure of the Nervous SystemThe nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).Central Nervous System (CNS)The CNS includes the brain and the spinal cord. The brain is the command center of the nervous system and is responsible for processing and interpreting sensory information, initiating movements, and regulating bodily functions. The spinal cord serves as a communication pathway between the brain and the rest of the body and is involved in controlling reflexes.Peripheral Nervous System (PNS)The PNS consists of nerves that extend from the CNS to the rest of the body. It is further divided into the somatic nervous system and the autonomic nervous system.- The somatic nervous system controls voluntary movements and is responsible for transmitting sensory information from the body to the CNS.- The autonomic nervous system regulates involuntary bodily functions such as heart rate, digestion, and respiration. It is further divided into the sympathetic and parasympathetic nervous systems, which have opposing effects on the body's physiological responses.NeuronsNeurons are the functional units of the nervous system. They are specialized cells that are capable of receiving, processing, and transmitting electrical and chemical signals. Neurons have a unique structure that allows them to carry out these functions.- Cell Body: The cell body contains the nucleus and other organelles necessary for the neuron's metabolic activities.- Dendrites: Dendrites are short, branching extensions that receive signals from other neurons and transmit them to the cell body.- Axon: The axon is a long, single extension that carries signals away from the cell body and transmits them to other neurons, muscles, or glands. Some axons are covered by a fatty substance called myelin, which insulates the axon and facilitates the rapid transmission of signals.- Synapse: The synapse is the junction between two neurons where electrical or chemical signals are transmitted from one neuron to another.Types of NeuronsThere are three main types of neurons, each with specific functions:- Sensory Neurons: Sensory neurons transmit sensory information from the body to the CNS. They have specialized receptor cells that detect stimuli such as touch, temperature, pain, and pressure.- Motor Neurons: Motor neurons carry signals from the CNS to muscles and glands, initiating movement and regulating bodily functions.- Interneurons: Interneurons connect sensory and motor neurons within the CNS and are involved in processing and integrating information.NeurotransmittersNeurotransmitters are chemical messengers that transmit signals between neurons and other cells. They are released from the presynaptic neuron into the synaptic cleft, where they bind to specific receptors on the postsynaptic neuron, initiating a response. There are many different types of neurotransmitters, each with specific functions and effects on the body.Examples of neurotransmitters include:- Acetylcholine: Acetylcholine is involved in the transmission of signals across neuromuscular junctions and is also found in the autonomic nervous system.- Dopamine: Dopamine is associated with motivation, reward, and movement control.- Serotonin: Serotonin is involved in mood regulation, appetite, and sleep.- Gamma-Aminobutyric Acid (GABA): GABA is an inhibitory neurotransmitter that helps regulate anxiety, stress, and neuronal excitability.NeuroplasticityNeuroplasticity refers to the ability of the nervous system to adapt and reorganize in response to experience, injury, or disease. It is a fundamental property of the brain and underlies learning, memory, and recovery from brain injuries.Types of NeuroplasticityThere are two main types of neuroplasticity:- Synaptic Plasticity: Synaptic plasticity refers to the ability of synapses to strengthen or weaken in response to activity. This process underlies learning and memory formation.- Structural Plasticity: Structural plasticity involves changes in the structure of neurons and their connections, such as the growth of new dendrites or the formation of new synapses. It plays a crucial role in recovery from brain injuries and in the maintenance of brain function.Neuroplasticity and LearningNeuroplasticity is essential for learning and memory formation. When we learn new information or skills, the connections between neurons are strengthened, leading to changes in brain structure and function. This process allows the brain to adapt to new experiences and to store and retrieve information.Neuroplasticity and Brain RepairNeuroplasticity also plays a critical role in the brain's ability to repair and reorganize itself following injury or disease. After a stroke or traumatic brain injury, for example, the brain can undergo structural and functional changes that enable the recovery of lost functions. This process can be enhanced through rehabilitation and targeted therapy.Factors Affecting NeuroplasticitySeveral factors can influence the extent and effectiveness of neuroplasticity, including:- Age: Neuroplasticity is most pronounced in the developing brain but continues throughout life to a certain extent. Younger brains are generally more malleable and responsive to change.- Experience: Experience and environmental enrichment can promote neuroplasticity by stimulating the formation of new connections and the growth of neurons.- Hormones and Neurotransmitters: Hormones and neurotransmitters play a crucial role in regulating neuroplasticity, influencing the strength and stability of synaptic connections. Disorders Affecting the Nervous SystemThe nervous system can be affected by a wide range of disorders that impair its function and can have far-reaching effects on the body. Some common disorders include:- Neurodegenerative Diseases: Neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS) are characterized by the progressive degeneration of neurons, leading to cognitive decline, movement disorders, and loss of muscle function.- Stroke: A stroke occurs when blood flow to a part of the brain is interrupted, resulting in damage to brain tissue and loss of function. Strokes can cause paralysis, speech and language difficulties, and cognitive impairments.- Multiple Sclerosis (MS): MS is an autoimmune disease that affects the central nervous system, causing damage to the myelin sheath and impairing the transmission of signalsbetween neurons. Symptoms of MS can vary widely and may include muscle weakness, sensory disturbances, and cognitive deficits.- Epilepsy: Epilepsy is a neurological disorder characterized by recurrent seizures, which are caused by abnormal electrical activity in the brain. Seizures can vary in severity and may involve loss of consciousness, convulsions, or abnormal sensations.Treatment and Management of Nervous System DisordersThe treatment and management of nervous system disorders depend on the specific condition and its underlying causes. Strategies may include:- Medications: Many nervous system disorders can be managed with medications that target symptoms or underlying disease processes. For example, antiepileptic drugs can help control seizures in epilepsy, while dopamine replacement therapies are used to manage symptoms of Parkinson's disease.- Rehabilitation: Rehabilitation programs, including physical therapy, occupational therapy, and speech therapy, can help individuals regain lost function and improve their quality of life following a neurological injury or illness.- Surgical Interventions: In some cases, surgical interventions may be necessary to address structural abnormalities or to relieve pressure on the brain or spinal cord. Examples include brain surgery for the removal of tumors and spinal fusion surgeries for the treatment of spinal cord injuries.- Lifestyle Modifications: Lifestyle modifications such as regular exercise, a healthy diet, and stress management can play a crucial role in supporting overall brain health and reducing the risk of certain neurological disorders.ConclusionThe nervous system is a remarkable and complex system that plays a vital role in every aspect of human functioning. Understanding its structure and function is essential for appreciating the intricate mechanisms that underlie our thoughts, emotions, movements, and bodily functions. By studying the nervous system, we can gain insights into the nature of consciousness, perception, and the fundamental mechanisms that govern our existence. Continued research and advancements in the field of neuroscience hold the promise of improving our understanding of the nervous system and developing new treatments for neurological disorders.。

以人的大脑和身体的作用为题写一篇英语作文The human brain and body work together in a complex and intricate manner to allow us to think, move, feel, and experience the world around us. The brain, which is often referred to as the body's control center, is the most important part of the nervous system. It is responsible for processing information, making decisions, and controlling our actions.The brain is divided into different areas, each with its own specific functions. The frontal lobe, for example, is involved in decision-making and problem-solving, while the occipital lobe is responsible for processing visual information. The brain also communicates with the rest of the body through the spinal cord and a network of nerves.In addition to the brain, the body's physical structure also plays a crucial role in how we function. Our muscles, bones, and organs work together to allow us to move, breathe, digest food, and perform a wide range of other tasks. The body is also equipped with a complex immune system that helps protect us from illness and infection.The brain and body work together in a seamless and coordinated manner to ensure our survival and well-being. Forexample, when we touch a hot stove, our nerve endings send a signal to the brain, which then sends a message to the muscles to pull our hand away. Similarly, when we feel hungry, the brain signals the stomach to release digestive enzymes to break down food.The brain and body are also interconnected in more subtle ways. For example, research has shown that our mental and emotional state can have a direct impact on our physical health. Chronic stress, for instance, has been linked to a variety of health problems, including heart disease, obesity, and depression.Overall, the relationship between the brain and body is a complex and dynamic one. By understanding how these two systems interact and influence each other, we can gain a deeper appreciation for the incredible capabilities of the human mind and body.。

大脑和人体的作用英语作文
大脑和人体的作用英语作文The Role of the Brain and the Human Body.The human body is a remarkable creation, with each part playing a crucial role in enabling us to function optimally. Among all the organs and systems, the brain stands out as the most complex and essential, controlling not only our cognitive abilities but also our physical movements, emotions, and senses. In this essay, we will delve into the significance of the brain and the human body, exploringtheir interconnectedness and the remarkable ways they work together to keep us alive and thriving.Let's start with the brain, the command center of our bodies. The brain is made up of billions of neurons, which are connected to each other through an intricate network of synapses. This network allows for the transmission of electrical signals, enabling communication betweendifferent regions of the brain and allowing us to process information, make decisions, and control our actions. Thebrain is responsible for our cognitive functions, including memory, perception, thinking, and consciousness. It receives input from our senses, interprets it, and then generates appropriate responses.The brain is also responsible for our emotions. It processes and regulates our emotional responses to external stimuli, allowing us to experience a range of emotions that shape our interactions with the world. The amygdala, for instance, plays a crucial role in emotional processing, regulating our responses to fear and pleasure.Moreover, the brain controls our motor functions, coordinating the movements of our muscles and limbs. The motor cortex, located in the frontal lobes, sends signals to the muscles, telling them how to contract and relax, enabling us to perform a wide range of movements.The human body, on the other hand, provides the physical framework for the brain to function. The skeletal system supports the body, protecting the brain and other vital organs. The muscular system, controlled by the brain,allows us to move and interact with our environment. The cardiovascular system pumps blood throughout the body, delivering oxygen and nutrients to the brain and removing waste products. The respiratory system supplies the brain with oxygen, essential for its functioning.The brain and the body are also closely connected through the endocrine system. This system produces and releases hormones that regulate various bodily functions, including metabolism, growth, and reproduction. The hypothalamus, a region of the brain, plays a key role in regulating the endocrine system, ensuring that the body's hormonal balance is maintained.The interconnectedness of the brain and the body is further emphasized by the concept of neuroplasticity. This refers to the brain's ability to change and adapt in response to external stimuli and experience. For instance, when we learn a new skill, the brain forms new neural connections to facilitate this learning. Similarly, physical activity can stimulate the growth of new neurons and improve the efficiency of neural networks, leading tobetter cognitive and motor performance.In conclusion, the brain and the human body are intricately connected, working together to enable us to function as highly complex and adaptive organisms. The brain controls our cognitive, emotional, and motor functions, while the body provides the necessary support and regulation for the brain to function optimally. Understanding the role of the brain and the body in our lives is crucial for appreciating the wonder and complexity of the human being.。

Neuropsychiatry_for_Past,_Today_and_Future(神经精神科学的
International Journal of Psychiatry and Neurology 国际神经精神科学杂志, 2012, 1, I-IV doi:10.4236/ijpn.2012.11001Published Online February 2012 (/journal/ijpn)Neuropsychiatry for Past, Today and Future——For the Launch of International Journal of Psychiatry and NeurologyJun YangNeurologist and PharmacistEditor-in-Chief of International Journal of Psychiatry and NeurologyDean and Professor, College of Pharmacy, Xinxiang Medical UniversityNeuropsychiatry, which has been persecuting the global, is the branch of medicine dealing with mental disorders attributable to diseases of the nervous system. “Chinese Mental Health Plan (2002-2010)” reported that there were abort 450 million people suffering from mental disorders in the world which bore 11% burden of the global medical cost in 2002. About 20% people had mental disorder problems in USA depending on 2003 report of the United States Presi-dent's New Freedom Commission on Mental Health. In 2009 China Disease Prevention and Control Health Center pub-lished the data of over 100 million people with neuropsychiatric diseases in China. Neuropsychiatry including the fields of psychiatry and neurology, has become a frontier of human scientific research, and a lot of countries have been paying close attentions to brain function study so as to understand the psychological activities, specially in neuro-psychiatric processes.Response to the fast development of neuropsychiatric science, we launched an international Chinese journal—Inter- national Journal of Psychiatry and Neurology, which was focusing on neuropsychiastric achievements and establishing an exchange platform for neurologists, psychiatrists, clinicians and researchers to share their opines about basic and clinic study in the field of neuropsychiatry.1. Past of NeuropsychiatryThe symptom, diagnosis and treatment of neuropsychiatric disorders have been written in ancient medical books. The mental disorders (心疾) and brain diseases (首疾) were recorded in Chinese oracle 3600 years ago. A famous medical scientist and father of neuropsychiastry in ancient Greece, Hippocrates of Cos II (460-377 BC) proposed that mental activities were caused by humoral pathology depending on his theory that the brain contraled the thinking. In 300-200 BC, “Inner Canon of the Yellow Emperor—The Miraculous Pivot-Crazy Section” 《黄帝内经——灵枢·癫狂篇》was the first book to discuss the relationship between the brain and mental activities. A France doctor Phillipe Pinel (1754-1826) was the first director of “Crazy Hospital” in the world. Dr. Rush Benjamin, father of neuropsychiatry in American, suggested that the programs of psychiatric and biological medicine should be opened for medical students 200 years ago. In 1845 Dr. Wilhelm Griesinger, a German scientist, proved first time that neuropsychiastric disorder was a kind of brain disease in his article. In 1902 Albany General Hospital in USA established the first department of neuropsychiatry.2. Today of NeuropsychiatryFollowing the scientific and technological development, especially the great achievements in neuroscience and mo-lecular biology, we can use multidisciplinary skills integrating the basic and clinic to study the neuropsychiatric diseases at the level of molecular, cell and body. Neurological diseases cause mental disorders, as while as mental diseases change the brain function usually. It has promoted for the neuropsychiatric disease study to use the basic neuroscientific skills inlcuding neuroanatomy, neurophysiology, neurobiochemistry, neuroimmunology, neuropharmacology and so on, to find the susceptibility gene, clear the neuroanatomic location, understand the neurological control process and ana-lyze the advanced brain function. On the other hand, it has verified the basic research results of neuropsychiatry by the clinical study data, genetic pedigree brain bank and non trauma resonance imaging skills.It has been explained the neuropsychiatric origins in the fields of gene, brain function and psychopharmacology. The interactions between neurocells and special chemical substances in neurocells make us deeply recognize the brain func-tion at the level of the membrane, receptor, transmitter, nucleus acid and so on, and understand the process of neuro-psychiatric diseases.Molecular genetics causes the research activities in neuropsychiatric diseases based on their high heritability. It makes a great success to find the new susceptibility gene by the genome wide association studies (GWAS) and systemic biological method.It searches the biological diagnosis markers of neuropsychiatric diseases by the methods of brain morphology and function. For example, we can comprehen the dopamine way change through the tracer 18F-FDOPA showing the pre-synaptic dopamine receptors after positron-emission tomography (PET)/Computer tomography (CT), and we can also acquire more biological information by combining neurological cognitive surveys.It makes a great progress in research and development of neuropsychiatric drugs since chlorpromazine was found in 1952. Depending on the forecast of the World Health Organization (WHO) in 2002, it will reach to 14% for neuropsy-chiatric drug in the whole global medical market in 2020. Unfortunately, it only spent 6 years achieving this forecast in 2008, which it sold 104.8 billion US dollar in the global neuropsychiatric drug market. It showed very active in research and development of neuropsychiatric drugs past 10 years, in which many new neuropsychiatric drugs were approved into clinic trail research and some of them were launched.3. Future of NeuropsychiatryAfter the Clinical Antipsychotic Trials in Intervention Effectiveness (CA TIE) project supported by the National Insti-tute of Mental Health (NIMH) of USA, European Union (EU) spent huge funds to study the first episode of schizophre-nia. We usually found many “Big Projects” (huge funds), which related with multicenter and multidisciplinary, in the fields of neuroscience and psychiatry. In 2010 the National Institute of Health (NIH) of USA began the project of hu-man connection group plan to understand the brain interconnection, which included 9 institutes from USA, Italy, Ger-man and UK. It costs 40 million US dolors and uses the methods of nuclear magnetic resonance, task stimulation, mag-netoencephalography and structure analysis. One of projects should study 300 twins and 1200 health volunteers. “The mental health act of the People’s Republic of China (Draft)” was approved by the State Council Standing Committee of the People’s Republic of China in September 2011.In January 2010, Dr. Philip Campbell, Editor-in-Chief of Nature, suggested that the near 10 years should be defined as “10 years of neuropsychiatric disorder”. There have shown so many new discover, new development and new achievement in the field of neuroscience and psychiatry although it was not clear for the suggestion to influence the neuropsychiatric study. It is believed that it will change radically in the etiological cognition, diagnosis, treatment, prevention and control of neuropsychiatric diseases.神经精神科学的过去、现在和将来——《国际神经精神科学杂志》创刊词杨 俊教授、主任药师、研究员级高级工程师《国际神经精神科学杂志》主编、新乡医学院药学院院长神经精神疾病是以神经系统病变、行为、心理活动紊乱为主要表现的一组疾病。
神经调控英语
神经调控英语Neuroregulation refers to the process by which the nervous system regulates and controls various functions in the body. It plays a crucial role in maintaining homeostasis and ensuring the proper functioning of the body's organs and systems. In this article, we will explore the concept of neuroregulation and its significance in English.Neuroregulation encompasses a wide range of processes, including sensory perception, motor control, emotional regulation, and cognitive functions. It involves the interaction between the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which consists of nerves that connect the CNS to the rest of the body.One of the key aspects of neuroregulation is the communication between neurons, which are specialized cells that transmit electrical and chemical signals in the nervous system. Neurons communicate with each other through synapses, which are junctions where signals are transmitted from one neuron to another. This communication allows for the coordination of various bodily functions and responses.The regulation of sensory perception is an essential aspect of neuroregulation. The sensory organs, such as the eyes, ears, nose, and skin, detect external stimuli and convert them into electrical signals that are transmitted to the brain. The brain then processes these signals and generates appropriate responses, such as perceiving visual images, hearing sounds, smelling odors, and feeling touch and pain.Motor control is another critical function regulated by the nervous system. The brain sends signals to the muscles through the spinal cord, enabling voluntary movements. This process involves the coordination of various muscle groups and requires precise control and timing.Emotional regulation is also influenced by neuroregulation. The limbic system, which is a set of brain structures involved in emotions, plays a crucial role in regulatingemotional responses. It helps to modulate feelings such as fear, happiness, sadness, and anger, allowing individuals to adapt and respond appropriately to different situations.Cognitive functions, including memory, attention, and problem-solving, are intricately linked to neuroregulation. The brain processes information received from the environment and stores it as memories. Attention allows individuals to focus on relevant stimuli and filter out distractions. Problem-solving involves the ability to analyze information, generate solutions, and make decisions.Disruptions in neuroregulation can lead to various neurological disorders and conditions. For example, Parkinson's disease is characterized by the degeneration of neurons involved in motor control, resulting in tremors, stiffness, and difficulty with movement. Attention deficit hyperactivity disorder (ADHD) is associated with difficulties in attention and impulse control. Alzheimer's disease affects memory and cognitive functions.In conclusion, neuroregulation is a fundamental process that underlies the functioning of the nervous system. It encompasses sensory perception, motor control, emotional regulation, and cognitive functions. Understanding neuroregulation is crucial for diagnosing and treating neurological disorders and optimizing overall brain health. By studying and exploring the intricacies of neuroregulation, we can gain valuable insights into the complexities of the human brain and its impact on our daily lives.。

Main Components
Soma: Cell body Axon: Transmitting process Dendrite: Receiving process Synapse: Gap between eurons; Transmission occurs over synapse
A: Immediate B: 24 hours C: 48 hours
Synaptic Transmission
Action potential: Calcium-gated channels open in axon terminal. Transmitter-containing vesicles bind to presynaptic membrane and release transmitter into synapse. Membrane potential of postsynaptic terminal is changed by binding of transmitter at receptors. Change can be excitatory (EPSP) or inhibitory (IPSP)
Propagation of neural signaling: Postsynaptic changes from dendrites passively spread intracellularly. If sum of EPSPs reaches threshold, then action potential is generated, repeating process.
Green dots: axon terminals
Red processes: dendrites
