TLDR
Good agreement is found between the distribution of hippocampal acetylcholinesterase and the patterning of silver grains after injection of [3H]leucine into the medial septum and diagonal bands and those cells labelled after injections of horseradish peroxidase into the hippocampus coincide.Abstract:
The origins, distribution, and cellular targets of the septo-hippocampal projections are reviewed. It appears that the distribution of acetylcholinesterase-positive neurons in the medial septum and diagonal bands and those cells labelled after injections of horseradish peroxidase into the hippocampus coincide; however, the possibility of a non-acetylcholinesterase septal projection remains. Good agreement is found between the distribution of hippocampal acetylcholinesterase and the patterning of silver grains after injection of [3H]leucine into the medial septum. A major target of septal efferents to the hippocampus is the interneuron population; the possibility of septal mediation of intrahippocampal circuitry via this anatomical arrangement is discussed.read more

TL;DR: The distribution of serotonin-1 (5-HT1) receptors in the rat brain was studied by light microscopic quantitative autoradiography and the existence of 'selective' areas allowed a detailed pharmacological characterization of these sites to be made in a more precise manner than has been attained in membrane-binding studies.

Cellular bases of hippocampal EEG in the behaving rat.
TL;DR: Movement-related RSA was correlated with a decrease in firing rate of pyramidal cells and an increase in the firing of both interneurons and granule cells, and Gradual phase-shifts of RSA were observed both in CA1 and the dentate gyrus.

Cholinergic projections from the basal forebrain to frontal, parietal, temporal, occipital, and cingulate cortices: A combined fluorescent tracer and acetylcholinesterase analysis
TL;DR: The morphologies, intercellular organization, and cortical projection patterns of putative cholinergic neurons in the basal forebrain of the rat were examined by use of fluorescent tracer histology in combination with the pharmacohistochemical regimen for acetylcholinesterase (AChE).

TL;DR: 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.

TL;DR: Variations in incubation times and reagent concentrations resulted in significant differences in the extent to which transported HRP could be demonstrated with benzidene, which demonstrated a wider extent of HRP transport than a representative diaminobenzidene procedure.
