This article is a commentary on "A role for the medial temporal lobe in feedback-driven learning: evidence from amnesia" by Foerde, K., Race, E., Verfaellie, M.,and Shohamy, D. (2013). It covers the idea that environmental feedback plays an important role with respect to both basal ganglia and hippocampus based learning. Evidence that both the hippocampus and the striatum are involved in reinforcement learning is given. This article suggests that future research use a more precise measurement of the two structures’ sensitivities to delay. The general picture suggests that the basal ganglia and the hippocampus share overlapping sensitivity to reinforcement signals, although at a different timescale.
