Updating the Lamellar Hypothesis of Hippocampal Organization
TLDR
It is suggested that longitudinal axons in the dentate gyrus may mediate “lateral” inhibition and define lamellar function, rather than undermine it, and the functional implications of longitudinally projecting axons depend not on whether they exist, but on what they do.

Anatomical Organization of the Parahippocampal‐Hippocampal Network
TLDR
The terminal organization of the presubicular input to the medial entorhinal cortex indicates that the interactions between the deep and superficial entorHinal layers may be influenced by this input.

Connection matrix of the hippocampal formation: I. The dentate gyrus
TLDR
A review of the quantitative neuroanatomy of the rodent dentate gyrus is presented in the context of the development of a computational model of its connectivity, which provides valuable clues in this regard.

Functional organization of the hippocampal longitudinal axis
TLDR
Together, anatomical studies and electrophysiological recordings in rodents suggest a model in which functional long-axis gradients are superimposed on discrete functional domains, which provides a potential framework to explain and test the multiple functions ascribed to the hippocampus.

TLDR
The results of the present study do not support the proposition that the deep hilar region is an extension of the pyramidal layer of the hippocampus as suggested by Lorente de Nó ('34), and thus CA4 is a misnomer.

Organization of intrahippocampal projections originating from CA3 pyramidal cells in the rat
TLDR
The distribution of intrahippocampal projections arising from the CA3 region of the rat hippocampus was investigated using in vitro and in vivo methods and bore numerous varicosities that electron microscopy confirmed to be presynaptic boutons.
Connections of the parahippocampal cortex in the cat. V. Intrinsic connections; comments on input/output connections with the hippocampus
TLDR
It appears that within the parahippocampal cortex of the cat a framework exists, which is composed of longitudinal and transverse connections, organized according to three principles: Medially directed projections originate mostly in superficial layers, whereas laterally directed fibers come from deep layers.
Origin and termination of the hippocampal perforant path in the rat studied by silver impregnation
TLDR
A detailed study of the origin and termination of the so‐called perforant path of the hippocampal region has been made in the rat, finding the origin to be in the medial part of the entorhinal area, from the most dorsal to the most ventral levels.

TLDR
All PHA‐L injections resulted in the labeling of axons projecting longitudinally within the entorhinal area, in both dorsal and ventral directions, albeit the ventral projections were the most prominent ones.
