MATH 190 Lecture Notes - Lecture 4: Affective Neuroscience, Fear Conditioning, Behavioral Activation
Document Summary
Two fathers of affective neuroscience: charles darwin"s book the expression of the emotions in man and animals 2 important points, animal emotions are homologues for human emotions a logical extension of darwin"s early work on evolution. Influence on affective neuroscience: promoting the use of research in animals to understand emotions in humans, giving impulse to scientists who held the view that different basic emotions had separable neural substrates. Recent criticism on cannon"s claims: emotional responses can be distinguished (at least partly) on the basis of autonomic activity, emotions were less intense when the brain was disconnected from the viscera in cannon"s studies. Some artificial manipulations of organ activity can induce emotions. Sham rage: decorticated cats were liable to make sudden, inappropriate & ill-directed anger attacks. Cannon & bard argued that if emotions were the perception of bodily change, then they should be entirely dependent on having intact sensory & motor cortices.
