Graphical abstract text
The dorsal subiculum is the primary source of hippocampal projections to
the rat retrosplenial cortex. Disruption of the subiculum to
retrosplenial projections impaired spatial working memory whenever the
test variant created a conflict between cue-types, associated with a
switch between different strategies. These findings suggest that the
direct projections from the dorsal subiculum to the granular
retrosplenial cortex help to maintain the flexible integration of
different spatial cue-types.
