subiculum

Offline ventral subiculum-ventral striatum serial communication is required for spatial memory consolidation

The hippocampal formation is considered essential for spatial navigation. In particular, subicular projections have been suggested to carry spatial information from the hippocampus to the ventral striatum. However, possible cross-structural communication between these two brain regions in memory formation has thus far been unknown. By selectively silencing the subiculum-ventral striatum pathway we found that its activity after learning is crucial for spatial memory consolidation and learning-induced plasticity.
