dentate granule neuron

Function: - granule cells of the dentate gyrus the principle neurons of the granule cell layer, a layer with a prominant dendritic arborization (molecular layer) - the hilus of the dentate gyrus contains neuroblasts that form granule cells from birth into old age. - newly formed granule cells accumulate under the older granule cells gradually increasing the thickness of the granule layer throughout life [2] * The human dentate gyrus contains about 9 x 10E6 granule cells. Comparative biology: - dentate granule cells of the rat have apical dendrites only - many dentate granule cells in humans & monkeys also have basal dendrites [2] Afferents: - entorhinal cortex (perforant pathway) Efferents: 1) cornu ammonis CA3 pyramidal cells (mossy fiber pathway) 2) cells of the of the dentate gyrus do not project outside of the hippocampal formation
