Positive and negative memories and behaviors are split up in the brains of mice

(RIKEN) Within the amygdala, an important memory center in the brain, pleasant experiences, tastes, and smells are confined to the back of the basolateral nucleus, while unpleasant ones are stored at the front. These anterior and posterior regions also interact in a push-pull manner, regulating behaviors tied to negative and positive stimuli, respectively. As reported on Oct.
