Evidence for a second hippocampal efferent pathway to hypothalamus and basal forebrain comparable to fomix system: a unit study in the awake monkey

Extracellular microelectrode techniques were used to investigate the influence of anterior and posterior hippocampal volleys on hypothalamic, basal forebrain, and preoptic unit activity in the awake primate with complete bilateral lesions of the fornix system. The results are interpreted in conjunction with data from a previous study in the intact primate.
