Figure 9

Schematic drawings of the 28 different types of amacrine cells encountered. Smooth or varicose narrow-field amacrine cells (15 types) were mono- (9 types) or multistratified (6 types). The three displaced amacrine cell types (somas in the GCL) found were all monostratified within the ON sublamina. Among the multistratified types, two stood out not only by their stratification depth, but also because they had the morphology of 'spidery' amacrine cells described in mammals [37]. Five types of medium-field amacrine cells and eight types of wide-field amacrine cells were found, which also came in smooth and varicose varieties and all showed characteristic stratification (mono- versus multistratified and depth of stratification). The location of black somas indicate where the majority of cells within this subtype had their somas (closest to the IPL, closest to the bipolar/outer half of the INL or inbetween these two layers). The locations of somas of subtypes shown in grey were randomly distributed throughout the inner nuclear layer. GCL, ganglion cell layer; INL, inner nuclear layer; IPL, inner plexiform layer. Scale bar = 10 μm.
