Fig. 7.

Tangential cut through layer I at midgestation (E89). A, Cell processes, probably dendrites, emerging from both poles of this bipolar C–R cell. Close contact with the dendrite of another cell is indicated with thearrow. Much smaller cells represent either non-C–R cells or glial cells. B, Lipofuscin-filled inclusion in the cell body of another C–R cell (arrow).C, Whirl of endoplasmic reticulum in the C–R cell process. D, C–R cells close to a bv, with an axon emerging from one end of the cell body (arrow) and a dendritic process emerging from the opposite end. Scale bars, 5 μm.
