Figure 13. AI and AII amacrine cells
display complex networks. A: Transmission electron microscope
(TEM) section 062 shows γ+ AI AC 4943 and neighboring BCs and ACs
(green) with a magenta GABA overlay. B: γ+ AI amacrine cell
4943 (red) spans the width of the RC1 volume and some of the cells
associated with it are rod bipolar cells 518, 5923, 8586; OFF cone
bipolar cell 5539; G+ AII amacrine cell, 476; G+ OFF amacrine cell,
7188. The circles over the proximal dendrites of amacrine cell 4943
denote sites of multiple amacrine cell synaptic inputs. C: Rod
bipolar cell 8586 synapses onto AI AC 4943. D: AI AC 4943 onto
synapses rod bipolar cell 5923. E: G+ AC 7188 makes a conventional
synapse on AI AC 4943. F: AI AC 4943 receives serial
conventional synapses. E denotes glutamate; G denotes glycine. The
letter colors match the profiles in the image. The main panel is from
section 168 and the yellow panel insert is from section 165.
