Activation of polyaxonal wide-field amacrine cells (ACs) by global jitter motion suppresses firing of specific GCs, such as the local motion detector (fast OFF GC in salamander, ON brisk transient GC, and ON-OFF direction selective GC in rabbit; (19) W3B GC in mouse (20)).
Vulnerability of dopaminergic amacrine cells and optic nerve myelination to prenatal endotoxin exposure.
Close relationships have been observed between 5-HT and GABA in vertebrates, such as the rabbit (Osborne & Beaton 1986) and the cat (Wassle & Chun 1988), with double-labeling studies demonstrating the coexistence of these 2 neurotransmitters in amacrine cells of the retina.
However, all those studies had failed to detect any regenerated inner retina nerve cells, except when the Muller glia cells were genetically modified with genes that specifically promote the formation of amacrine cells, which act as intermediaries in transmitting nerve signals.
In the normal retina (Figure 6(a)), anti-GABA antibody labels the inner plexiform layer (IPL), the amacrine cells located on the inner lamina of the INL, and the horizontal cells located on the outer lamina of the INL.
