Hippocampal electrical activity I. Morphological aspects

Abstract 1. 1. The histology of the hippocampus in the rat and rabbit was studied by electron microscopy with the object of relating the geometrical configuration of hippocampal cells to hippocampal electrical activity. 2. 2. Measurements of the hippocampus of the rabbit were made by light microscopy. 3. 3. A striking feature of the hippocampus is the relationship between glial processes and synaptic endings. 4. 4. Particular attention was paid to extraneuronal spaces where extracellular currents may flow.
