Localization and Release of Glutamic Acid in Relation to the Hippocampal Mossy Fibre Pathway

Abstract

ABUNDANT clinical and experimental evidence indicates that the hippocampus is involved in temporal lobe epilepsy1,2. Some of the symptoms of excitation associated with the disease may be related to the marked tendency of the hippocampus to produce seizures in response to mechanical, electrical and chemical stimuli3. Focal discharges in the temporal lobe could spread through direct afferents to the nearby entorhinal cortex4. Excitatory projections from entorhinal neurones form the final link in the chain between the sensory neocortex and the hippocampus by making synaptic contact with granule cells of the dentate gyrus. Axons arising from the granule cells synapse, in turn, on the apical dendrites of CA3–4 hippocampal pyramidal cells. These axons comprise the mossy fibre pathway5.
