Ventral Striatum Lesions Do Not Affect Reinforcement Learning With Deterministic Outcomes on Slow Time Scales

A large body of work has implicated the ventral striatum (VS) in aspects of reinforcement learning (RL). However, less work has directly examined the effects of lesions in the VS, or other forms of inactivation, on 2-armed bandit RL tasks. We have recently found that lesions in the VS in macaque mon...
