This central brain region is implicated a diversity of brain disorders, but its function is not understood.

We started by looking at genes expressed selectively in the hippocampus, and found an unusual constellation of receptors and signaling molecules, prompting the speculation that part of the function of the hippocampus is in sensing internal hormones and metabolites.
