ORIGINS OF THE AFFERENTS TO THE HIPPOCAMPUS IN THE RAT——HRP METHOD / 解剖学报

ABSTRACT

The afferent projections to the hippocampus were studied with HRP. Thirty three per cent solution of HRP was slowly injected into the dorsal or ventral hippocampus on its right side in 25 albino rats and HRP-labelled cells were found in the following nuclei1. On the ipsilateral side entorhinal cortex, medial septal nucleus, supramammillary nucleus, submammillothalamic nucleus, dorsal raphe nucleus, median raphe nucleus, locus coeruleus, diagonal band and nucleus of superior colliculus.2. On the contralateral side areas CA_3 and CA_4 of hippocampus and locus coeruleus.
