Ganglion cells possess a CACA-sensitive GABA receptor. (A) There is a GABA effect on barium current not due to the GABAAR, the baclofen sensitive GABABR, or the GABACR. When these receptors were blocked (GABAAR and GABACR) or saturated (GABABR), GABA still caused a reversible reduction in the voltage activated barium current. (B) Low doses of CACA reduced the barium current. (C) This effect of CACA was not blocked by a combination of antagonists that together block the GABAAR, GABACR, and the baclofen-sensitive GABABR.
