dentate gyrus

A curved gyrus hidden along the medial surface of the temporal lobe of each cerebral hemisphere. It contains a cortex of three layers, with a single cell layer, that is part of the hippocampal formation, and it is folded inside the hippocampal sulcus, where it lies against the subicular edge of the parahippocampal gyrus. The surface of the dentate gyrus has regularly-spaced transverse grooves, which make the gyrus resemble a row of teeth.
