第一章
1. The information-Processing Sequence in the Brain Is ①输入 ,②整合 ,3.输出
2. 各种高级认知功能在大脑皮质都有明确定位。对，
3. 从神经科学角度看，眼见为实这句话是正确的。错。
4. 简述脑损伤阻碍兴奋或抑制指令后的行为改变。
Brain injury produce either a loss of behavior or a release of behavior .Behavior is lost when the damage prevents excitatory instructions ;behavior is released when the damage prevents inhibitory instructions.
