Unit activity of 135 GCR-cells in rat's LGNd was recorded extracellularly using micropipettes filled with trypan blue for subsequent marking of recording sites. The latencies of responses to electrical stimulation of the optic chiasma (OX) were mapped, and in accordance with Fukuda (1973) each GCR-cells was classified as fast or slow. Fast cells predominate in the rostroventromedial subregion and slow cells in the caudal part. Both fast and slow subtypes were found in the remaining rostrodorsolateral zone where slow cells made up two thirds of the subsample. The results fit the suggestion that in the LGNd of rats a fast retino-geniculate pathway relays in the ventromedial region, whereas slow pathways exist in the caudal as well as in the dorsolateral zone.
使用充满台盼蓝的微电极细胞外记录大鼠外侧膝状体背核（LGNd）中135个膝状细胞的单位活动，以便随后标记记录位点。绘制对视交叉（OX）电刺激反应的潜伏期，并根据福田（1973年）将每个膝状细胞分类为快反应或慢反应。快反应细胞在吻侧腹内侧亚区占主导，慢反应细胞在尾侧部分占主导。在其余的吻背外侧区发现了快反应和慢反应两种亚型，其中慢反应细胞占子样本的三分之二。结果符合以下观点：在大鼠的外侧膝状体背核中，一条快速的视网膜-膝状体通路在腹内侧区域中继，而慢反应通路存在于尾侧以及背外侧区。
