The effects of iontophoretically applied gamma-aminobutyric acid (GABA) and glycine, and of their antagonists, bicuculline and strychnine, were compared between ganglion cells from the central and peripheral retinae of optically intact eyes in barbiturate-anaesthetised cats. The visual response of on-cells was inhibited by GABA and enhanced by bicuculline. The visual response of off-cells was inhibited by glycine and enhanced by strychnine. The sensitivity of cells to the transmitters was lower in the peripheral retina than in the area centralis, whilst the sensitivity to the antagonists was similar in both regions of the retina. Cells from the area centralis were inhibited by either GABA or glycine, but never both. Cells from the periphery were less selective and were inhibited by both transmitters.
在巴比妥类麻醉的猫中，比较了离子电渗法施加的γ-氨基丁酸（GABA）和甘氨酸及其拮抗剂荷包牡丹碱和士的宁对视力正常眼睛中央和周边视网膜神经节细胞的影响。开细胞的视觉反应被GABA抑制，被荷包牡丹碱增强。关细胞的视觉反应被甘氨酸抑制，被士的宁增强。周边视网膜细胞对递质的敏感性低于中央凹区域，而视网膜两个区域对拮抗剂的敏感性相似。中央凹区域的细胞被GABA或甘氨酸抑制，但不会同时被两者抑制。周边的细胞选择性较低，被两种递质都抑制。
