Amygdala and Ventral Striatum Make Distinct Contributions to Reinforcement Learning by Costa, Vincent D., Dal Monte, Olga, Lucas, Daniel R., Murray, Elisabeth A., Averbeck, Bruno B.

“…Reinforcement learning (RL) theories posit that dopaminergic signals are integrated within the striatum to associate choices with outcomes. Often overlooked is…”

Prefrontal mechanisms of behavioral flexibility, emotion regulation and value updating by Rudebeck, Peter H, Saunders, Richard C, Prescott, Anna T, Chau, Lily S, Murray, Elisabeth A

“…Existing data are consistent with a role for the orbitofrontal cortex (OFC) either in regulating emotion and enhancing behavioral flexibility or in updating…”

The anterior cingulate cortex is necessary for forming prosocial preferences from vicarious reinforcement in monkeys by Basile, Benjamin M, Schafroth, Jamie L, Karaskiewicz, Chloe L, Chang, Steve W. C, Murray, Elisabeth A

“…A key feature of most social relationships is that we like seeing good things happen to others. Research has implicated the anterior cingulate cortex (ACC) in…”

Visual perception and memory : A new view of medial temporal lobe function in primates and rodents by MURRAY, Elisabeth A, BUSSEY, Timothy J, SAKSIDA, Lisa M

“…The prevailing view of medial temporal lobe (MTL) function has two principal elements: first, that the MTL subserves memory but not perception, and second,…”

Balkanizing the primate orbitofrontal cortex: distinct subregions for comparing and contrasting values by Rudebeck, Peter H., Murray, Elisabeth A.

“…The primate orbitofrontal cortex (OFC) is often treated as a single entity, but architectonic and connectional neuroanatomy indicate that it has…”
