Document Summary
Early theories of emotion: affective neuroscience is the investigation of the neural basis of emotion and mood. The james - lange theory: we experience emotion in response to psychological changes in our body, you become scared because of your racing heart and tensed muscle. Interoceptive awareness: we can be aware of our body"s autonomic function: part of james lange theory. Difficulties with the concept of a single system for emotions: there isn"t a single emotion system. Fear and the amygdala: amygdala plays an important role in fear. 2: two pathways connect the amygdala with the hypothalamus, ventral amygdalofugal pathway, stria terminalis. In cats, lateral stimulation can elicit fear and violent aggression: brain activity in response to fearful faces showed more amygdala activity than in response to faces with neural expressions. A neural circuit for learned fear: memories for emotional events are long and vivid.
