Hippocampal long‐range GABAergic neurons target hippocampal‐projecting cells of the supramammillary area
The supramammillary area (SuM) is well known for its direct connections to, and varied impacts on, the hippocampus. In contrast, relatively little is known about connectivity in the reverse direction – that is, the hippocampal influence on the SuM. We find that the hippocampus provides direct GABAergic inputs to the Su...
