Direction-selective neurons in the rabbit lateral geniculate nucleus signal movement-direction more precisely than their retinal counterparts. This increased selectivity arises from the interaction of retinal inputs to the geniculate cell. A direction-selective geniculate neuron is fed by at least two retinal direction-selective cells, whose preferred directions are 180 degrees apart. One retinal input is excitatory to the geniculate cell and the other is inhibitory.
兔子外侧膝状核中的方向选择性神经元比其视网膜对应神经元更精确地信号运动方向。这种增强的选择性源于视网膜输入与膝状细胞的相互作用。一个方向选择性膝状神经元由至少两个视网膜方向选择性细胞提供输入，它们的偏好方向相隔180度。一个视网膜输入对膝状细胞起兴奋作用，另一个则起抑制作用。
