Fig. 6. (A,B). Topography of cells in the ganglion cell layer of the peafowl retina (right eye). (A) All cells excluding glia; (B) Presumptive ganglion cells only (see Fig. 1 and text for details of criteria used). In both cases a prominent area centralis, with the possibility of a visual streak of high density extending from the area centralis towards the nasal retina, is indicated. Lines represent isodensity contours; numbers represent x10³ cells mm^-2. The black dot at the centre of the retina represents the location of the highest density count obtained (35.6x10³ ganglion cells mm^-2 in B). D, V, T and N refer to the dorsal, ventral, temporal and nasal aspects, respectively. The approximate location of the pecten (p) is also shown.
