Complete Axon Arborization of a Single CA3 Pyramidal Cell in the Rat Hippocampus, and its Relationship With Postsynaptic Parvalbumin‐containing Interneurons
TLDR
It is concluded that the physiologically effective excitatory connections between single pyramidal cells and postsynaptic inhibitory neurons are mediated by a small number of contacts, mostly by a single synapse, which results in a high degree of convergence and divergence in hippocampal networks.
The hippocampal CA3 network: An in vivo intracellular labeling study
TLDR
The concentrated distribution of the axon collaterals (“patches”) indicates that subpopulations of neurons may receive disproportionately denser innervation, whereas innervation in the rest of the target zones is rather sparse.
Three-dimensional reconstruction of the axon arbor of a CA3 pyramidal cell recorded and filled in vivo
TLDR
It is suggested that the CA3 system can be conceptualized as a single-module, in which nearby and distant targets are contacted by the same probability (similar to a mathematically defined random graph), which appears ideal for segregation and integration of information and memories.
Axonal morphometry of hippocampal pyramidal neurons semi-automatically reconstructed after in vivo labeling in different CA3 locations
TLDR
To fully characterize the axonal diversity of CA3 principal neurons will require higher-throughput reconstruction systems beyond the threefold speed-up of the method adopted here.
Disposition of the slab‐like modules formed by axon branches originating from single CA1 pyramidal neurons in the rat hippocampus
TLDR
The hippocampus is thought to be an area where the neuronal circuits for short‐term memory or the cognitive map may reside and the projection of the CA1 pyramidal neurons in the rat dorsal hippocampus, especially in the subiculum, was studied by means of intracellular and extracellular HRP injection.
Pyramidal neuron types in field CA2 of the guinea pig
Projection of the entorhinal layer II neurons in the rat as revealed by intracellular pressure‐injection of neurobiotin
TLDR
This study shows that the entorhinohippocampal circuit is not a simple circle from single cells level, as well as investigating a component of the perforant path, projection of theEntorhinal layer II neurons.
Hippocampal CA1 interneurons: an in vivo intracellular labeling study
TLDR
Fast spiking interneurons in the CA1 area of the dorsal hippocampus were recorded from and filled with biocytin in anesthetized rats to indicate that interneURons with distinct axonal targets have differential functions in shaping the physiological patterns of theCA1 network.
Crossing fiber arrays in the rat hippocampus as demonstrated by three‐dimensional reconstruction
TLDR
An intracellular horseradish peroxidase study of the CA3 pyramidal neurons and the granule cells of the fascia dentata suggests that most myelinated fibers in the hippocampus are organized parallel to the alvear fibers, and proposes a new model of the organization of the intrinsic excitatory circuitry of the rat hippocampus which creates a crossing neural network.
Preservation of topography in the connections between the subiculum, field CA1, and the entorhinal cortex in rats
TLDR
The CA1 projection, rather than the subicular projection, is the main projection that feeds back information from the hippocampus to the entorhinal cortex, and the framework of the major hippocampal circuit proposed in previous studies should be reconsidered.

A light and electron microscopic analysis of the mossy fibers of the rat dentate gyrus
TLDR
The axon collaterals of dentate granule cells have been analyzed with the aid of a computerized microscope, following intracellular injections of horseradish peroxidase in hippocampal slice preparations, finding that they are confined to the hilar region and correlated with the location of the granule cell body.

The topographical organization of the hippocampal projection to the septal area: A comparative neuroanatomical analysis in the gerbil, rat, rabbit, and cat
TLDR
The findings indicate that the origin of the topographical projection to the medial and lateral septum are the dorsal and ventral hippocampus, respectively, which is unrelated to cytoarchitectonic fields within the hippocampus and is also invariant among the species considered in this study.

TLDR
The results of double retrograde tracer experiments indicated that the 2 densest projections from the lateral entorhinal area--to the medial prefrontal region and to the dentate gyrus and Ammon's horn--arise from essentially separate populations of neurons.
