PSYC 153 Lecture Notes - Lecture 10: Limbic System, Amygdala, Lesion
Document Summary
They want this stimulation so bad they will. We don"t need to have awareness of emotion at the cortex to have the emotion. High road: a lot more processing, that is where you have the conscious processing of the stimulus. See snake: your low road will have it. Response gets you to fight or flight: then high road will come in and tell you to suppress your response. When it is hyperactive more likely to have ptsd. Fear learning: shock with the tone, then have tone without the shock and the animal freezes, when amygdala was lesioned. Mouse was no longer associating the conditioned stimuli: lesion the cortex didn"t do anything. Humans will say they didn"t hear the tone but still have the stimuli. The low road- doesn"t use the cortex. What is special about faces: sm could not pick out what was fearful and not.
