Direct Inputs To Off Α And G9 Ganglion Cells From Aii Amacrine Cells In Rabbit Retina, Wei-Li Liu
Dissertations & Theses (Open Access)
In the mammalian retina, AII amacrine cells are essential in the rod pathway for dark-adapted vision. But they also have a “day job”, to provide inhibitory inputs to certain OFF ganglion cells in photopic conditions. This is known as crossover inhibition. Physiological evidence from several different labs implies that AII amacrine cells provide direct input to certain OFF ganglion cells. However, previous EM analysis of the rabbit retina suggests that the dominant output of the AII amacrine cell in sublamina a goes to OFF cone bipolar cells (Strettoi et al., 1992).
Two OFF ganglion cell types in the rabbit retina, …
