Reactivation in Ventral Striatum during Hippocampal Ripples: Evidence for the Binding of Reward and Spatial Memories?

The article discusses the reactivation in ventral striatum during hippocampal ripples. Research on primates and rodents has corroborated the essential role of the hippocampus in transforming new memories into stable representations elsewhere in the brain. Many theories of memory consolidation propose the reactivation of behavioral experiences, typically during periods of sleep or rest. Electrophysiological evidence for such theories has been recorded in hippocampal place cells in rats.
