Term: type (a) wide-field unistratified amacrine cell

Definition: This wide-field unistratified cell has a mean soma of 11.1 micrometers. A single dendrite arises from the cell soma before it branches on a plane. These branches, about 1 micrometer in diameter, then apss in many directions within that plane; the bifurcations that do occur are near the cell soma and the dendrites take a straingth line across the retina (see figure 4, plate 1, and figure 13). Type (a) and type (b) wide-field unistratified amacrine cells have been found with their cell bodies in either the inner nuclear layer or in the ganglion cell layer.
