Highlights
In behaving rats, BLA excites projection cells and vHPC excites interneurons in PL
BLA promotes fear-signaling in PL, whereas vHPC inhibits it
vHPC inhibits fear expression after, but not before, extinction
vHPC gates fear expression via the PL after, but not before, extinction

Highlights
The amygdala is necessary for deterministic and stochastic reinforcement learning
The ventral striatum is only necessary for learning stochastic reward associations
Amygdala and ventral striatum lesions decrease choice consistency
Ventral striatum lesions hasten choice reaction times leading to more errors

同じタスクでドパミンをコントロールしてベイズ/強化学習で行動モデルに当てはめています。ベイズは今回ぜんぜんダメでしたけど……。
