Abstract
The afferents to the parahippocampal area of the rat were studied with retrograde transport of horseradish peroxidase injected into the medial entorhinal cortex, lateral entorhinal cortex, parasubiculum, presubiculum, or a large injection which stained all these structures as well as the ventral hippocampus. Control rats were injected with horseradish peroxidase into the overlying visual cortex. Labeled neurons in brains with injections into the medial entorhinal cortex and the adjacent parasubicular region were found in the ipsilateral and contralateral presubicular region, the medial septal nucleus, the thalamic nucleus reuniens, the dorsal part of the lateral nucleus of thalamus, the anterior periventricular nucleus of the thalamus, and the dorsal raphe nucleus. Brains with injections into the lateral entorhinal cortex yielded labeled neurons in the medial septal nucleus, nucleus reuniens, dorsal raphe nucleus, and nucleus locus ceruleus. Injections into the presubiculum resulted, in addition, in labeling of neurons in the lateral nucleus of the thalamus. Control injections aimed at the sensory cortex overlying the parahippocampal area yielded labeled neurons in the medial septal nucleus, the dorsal lateral geniculate nucleus, and the nucleus locus ceruleus.
