pubmed:abstractText |
The light-evoked release of acetylcholine (ACh) from the rabbit retina was taken as a measure of cholinergic amacrine cell activity. The glutamate analogue DL-(+/-)-2-amino-4-phosphonobutyric acid (APB) prevented the light-evoked release of ACh and also selectively abolished the ON-responses of ganglion cells and the ERG b-wave. It is concluded that the input to cholinergic amacrine cells involves mainly the depolarizing bipolar cells, which subserve ON-channels. L-(+)-stereoisomer of APB was 15 times more potent than the D-(-)-isomer in suppressing ACh release and the b-wave, suggesting that the mechanism of action of APB does not involve antagonism of excitatory amino acids.
