Single cells were recorded in layers A and A1 of the cat dorsal lateral geniculate nucleus (dLGN) with multibarrel micropipettes. Interocular inhibition ("binocular inhibition") was elicited by phase-reversing gratings presented monocularly to the nondominant eye. This inhibition was blocked by microiontophoretic application of bicuculline and thus proven to be GABAergic. Cortical cooling enhanced the inhibition from the nondominant eye. After localized destruction of the receptive field area in the dominant eye, duration and strength of discharge depression were increased. It is concluded that afferent activity from the dominant eye reduces inhibition from the nondominant eye in the dLGN.
使用多管微电极在猫的背外侧膝状核（dLGN）的A层和A1层记录单细胞。通过向非优势眼单眼呈现相位反转光栅来诱发眼间抑制（“双眼抑制”）。这种抑制可通过微量离子电泳施加荷包牡丹碱来阻断，因此被证明是γ-氨基丁酸（GABA）能的。皮层冷却增强了来自非优势眼的抑制。在优势眼的感受野区域局部破坏后，放电抑制的持续时间和强度增加。得出的结论是，来自优势眼的传入活动减少了dLGN中来自非优势眼的抑制。
