Introduction to the hilus and mossy cells. (A) A schematic of the rat hippocampus from Amaral (1978) in horizontal section shows the location of the hilus (zone 4). GCL, granule cell layer; H, hilus; ML, molecular layer; MF, mossy fiber; PCL, pyramidal cell layer. (B) A drawing of a mossy cell from the same study (Amaral, 1978). (C) A mossy cell that was physiologically-identified in hippocampal slices from an adult male rat and filled with Neurobiotin from Scharfman et al. (2001). An arrow points to the axon; arrowheads point to thorny excrescences. Calibration = 20 μm.
