The medial perforant path synapses onto the proximal dendritic area of the granule cells, whereas the lateral perforant path does so onto their distal dendrites. Most lateral views of the dentate gyrus may appear to suggest a structure consisting of just one entity, but medial movement may provide evidence of the ventral and dorsal parts of the dentate gyrus.[22] The axons of the granule cells called mossy fibres, make excitatory synaptic connections with the pyramidal cells of CA3 and CA1.[20]
