In the early 1970s, Andersen and colleagues proposed that the principal excitatory
pathways of the hippocampal formation were organized in a lamellar fashion. This …

Mossy cells comprise a large fraction of the cells in the hippocampal dentate gyrus,
suggesting that their function in this region is important. They are vulnerable to ischaemia …

This study investigated the spatial distribution and cellular-synaptic generation of
hippocampal sharp waves (SPW) in the dorsal hippocampus of the awake rat. Depth …

The efferent connections of the hippocampal formation of the rat have been re‐examined
autoradiographically following the injection of small quantities of 3H‐amino acids (usually …

The intrahippocampal distribution of axon collaterals of individual CA3 pyramidal cells was
investigated in the rat. Pyramidal cells in the CA3 region of the hippocampus were …

The morphology of neurons in the “hilar region” of the hippocampus (fields CA3c and CA4 of
Lorente de Nó,'34) was analyzed with several variants of the Golgi technique. Hippocampi …

Neurogenesis in the rat hippocampal region was examined with 3H‐thymidine
autoradiography. The rats in the prenatal groups were the offspring of pregnant females …

Although the hippocampal formation must be regarded as a critical component of the
“medial temporal lobe memory system,” there is now convincing evidence that it does not …

The longer associational connections of the hippocampal formation have been studied
autoradiographically in a series of adult rats after small injections of 3H‐amino acids into …

By virtue of its precise internal organization and its postulated involvement in learning and
memory, the hippocampal formation has been the most extensively investigated brain …
