Neuroanatomy Overview
X-System - reflexive and automatic
Amygdala (AMY)
fear and other emotional reponses
emotional memory
Doral Anterior Cingulate (dACC)
an alarm that recruits the C-system
emotional distress to pain
bias
monitors conflict
Basal Ganglia (BG)
skill learning
habit and pattern formation, automatic
Lateral Temporal Cortex (LTC)
behavior identification
perception of objects/situations
Ventromedial Prefrontal Cortex (vmPFC)
generates emotional response by thought
the working memory of emotions and values
self and other
emotional regulation
Rostral Medial Prefrontal Cortex (rmPFC) person perception, mentalizing, processing self-referential information [THIS IS NOT LISTED IN THE COURSE's X system]
Ventral Striatum (VS)
reward
