Fig. 5.
(Color online) Contacts between PV++ amacrine cells and AII amacrine cells. PV++ amacrine cells (green) contacted calretinin-immunoreactive (CR-IR) AII amacrine cells (red) in S2 of the IPL in this flat mount from midperipheral macaque retina (5–10 mm from the fovea). Images are single 0.5-µm optical sections. (a) Separation of channels showing only (CR-IR) AII lobular dendrites (red). (b) Separation of channels showing only PV++ dendrites with varicosities (green). (c) Arrows indicate sites of PV++ varicosity (green) and AII lobular dendrite (red) interactions (yellow). Note that AII amacrine cell lobular dendrites are large in comparison to PV++ varicosities. Scale bar = 10 µm.
