Some internal pathways of the hippocampus were mapped in adult rats using Fink‐Heimer silver impregnation methods for the demonstration of anterograde axon degeneration. 
Commissural and intrinsic connections of the rat hippocampus

The commissural and intrinsic connections of the hippocampus were studied using the Fink‐Heimer method and the horseradish peroxidase (HRP) uptake technique.
The connections of the hippocampal region New observations on efferent connections in the guinea pig, and their functional implications *
TLDR
The efferent connections of the hippocampal region are dealt with, and the functional implications of these projections are considered.
Autoradiographic studies of the commissural and ipsilateral association connections of the hippocampus and dentate gyrus. I. The commissural connections
The commissural connections of the two major cytoarchitectonic fields of the hippocampus (fields CA1 and CA3) and of the dentate gyrus of the rat have been studied autoradiographically following

The organization of the reciprocal connections between the subiculum and the entorhinal cortex in the cat: I. A neuroanatomical tracing study
The connections between the subiculum (SUB) and the entorhinal cortex (EC) were studied in the cat with retrograde and anterograde tracing techniques.
Distribution of commissural afferents to the hippocampus of the rabbit
The commissural connections of the hippocampus (fascia dentata and Ammon's horn) were investigated in the rabbit using a Fink‐Heimer silver impregnation method after the transection of either or both
Distribution of acetylcholinesterase in the hippocampal region of the mouse: II. Subiculum and hippocampus
TLDR
The distribution of acetylcholinesterase was examined in the subiculum and hippocampus of the adult mouse and was compared with the cytoarchitectural fields and layers.
Selective hippocampal lesions and behavior
TLDR
Despite the often cited criticisms of the lesion technique, much of the evidence that relates to the authors' understanding of the functional involvement of different structures and systems in the brain is based on experiments involving damage to the brain.

Distribution of hippocampal mossy fibers in the rat. An experimental study with silver impregnation methods
TLDR
The distribution of the axons that arise in the fascia dentata and go to the hippocampus proper are dealt with by means of three‐dimensional reconstructions.
Cortical Afferents to the Entorhinal Cortex of the Rhesus Monkey
Although the entorhinal cortex is a major contributor of afferents to the hippocampus and dentate gyrus, knowledge of its own afferents has been vague. Regions of both the frontal and temporal lobes
Synaptic Adjustment after Deafferentation of the Superior Colliculus of the Rat
TLDR
It was found that synaptogenesis continues to give a near-normal ratio of terminals containing either spheroidal or flattened vesicles, and reinvasion of synaptic sites vacated by degenerate optic terminals occurs, with an incomplete return toward a normal proportion of synaptic types.
Hippocampal efferents to the ipsilateral entorhinal area: An experimental study in the rat
A hitherto undescribed pathway from the hippocampus to the entorhinal area has been found in the albino rat in experimental studies by the silver‐impregnation technique of Fink and Heimer ('67) and a
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.
Projection of the lateral part of the entorhinal area to the hippocampus and fascia dentata
TLDR
A third group of perforant fibers, bing intermediate to the others with regard to both origin and termination has been noticed in one animal.
Ipsilateral afferents to the commissural zone of the fascia dentata, demonstrated in decommissurated rats by silver impregnation

  • 1971
TLDR
An ipsilateral pathway to the commissural zone of the dentate fascia has been demonstrated in the rat using the Fink‐Heimer silver impregnation method and the resulting degeneration was shown to be of purely ipsilaterally origin.
Timm's sulfide silver reaction for zinc during experimental anterograde degeneration of hippocampal mossy fibers
TLDR
In the present study anterograde degeneration was produced in the mossy fibers in the rat by placing lesions in the fascia dentata, after which the Timm reaction was checked at different postoperative intervals.
