Receptive fields of 262 pulvinar neurons were studied. Receptive fields of 142 of these neurons were studied in detail with the aid of a stationary spot of light, flashing in different parts of the receptive field. Depending on responses to presentation of the stationary stimulus the neurons were divided into six groups. The first group included neurons with on-off responses to photic stimulation (44 of 142), the second group neurons with off responses only (42 of 142). In cells of the third group (19 of 142) an on response only was recorded in all structures of the receptive field tested. Neurons of the fourth group (eight of 412) had a receptive field of similar structure to that of the simple receptive fields of neurons in cortical area 17. The fifth group (10 of 142) included neurons with a receptive field of concentric structure, the sixth (19 of 142) consisted of neurons with receptive fields with multiple discharge centers. The structure of the receptive field of these neurons was mosaic, with an irregular distribution of exciting and "silent" zones. The mean responses latency of the pulvinar neurons was 40-70 msec. Responses of neurons with shorter (20 msec) and longer (130-160 msec) latent periods also were recorded.
对262个丘脑枕神经元的感受野进行了研究。其中142个神经元的感受野借助于一个固定光点在感受野的不同部位闪烁进行了详细研究。根据对固定刺激呈现的反应，这些神经元被分为六组。第一组包括对光刺激有开-关反应的神经元（142个中的44个），第二组是仅有关反应的神经元（142个中的42个）。在第三组细胞（142个中的19个）中，在所测试的感受野的所有结构中均记录到仅有开反应。第四组神经元（412个中的8个）的感受野结构与皮层17区神经元的简单感受野相似。第五组（142个中的10个）包括具有同心结构感受野的神经元，第六组（142个中的19个）由具有多个放电中心感受野的神经元组成。这些神经元感受野的结构呈镶嵌状，兴奋区和“沉默”区分布不规则。丘脑枕神经元的平均反应潜伏期为40 - 70毫秒。也记录到了潜伏期较短（20毫秒）和较长（130 - 160毫秒）的神经元反应。
