| 1CA amacrine retinal cell | Nguyen-Legros et al. (NL) | Two subpopulations of TH-immunoreactive (TH-I) cells, which actually contain dopamine (Nguyen-Legros et al., 1994), were first demonstrated in the rat retina. Both are amacrine cells (i.e., intraretinal axonless neurons mostly located in the innermost cell row of the inner nuclear layer [INL]). According to the terminology introduced by Mariani and Hokoc (1988), the type 1CA cells (alternatively called large THI-DA cells (Nguyen-Legros, 1987) CA1 cells (Mitrofanis and Provis, 1990) orAcells [Casini and Brecha, 1992]) are large-bodied, intensely TH-I neurons branching mostly in the outermost sublayer (sublayer 1) of the inner plexiform layer (IPL) (Figs. 1–4, 8 (black cell), 10, 15). A few 1CA cells are displaced to different levels of the IPL or to the GCL in both rodents and primates (Figs. 6–8 [green cell]), but their processes finally join the DA plexus of the IPL sublayer 1 (Martin-Martinelli et al., 1994; Nguyen- Legros et al., 1992). Interplexiform | is included | | All the IPCs analyzed belonged to the 1CA cell class, i.e., the large field monostratified, heavily TH-I cells (Nguyen-Legros et al., 1983; Mariani and Hokoc, 1988, Mitrofanis et al., 1988, Nguyen-Legros et al., 1992). | Savy C., Moussafi F., Durand J., Yelnik J., Simon A. & Nguyen-Legros J. | Mihail Bota |
