Recording the evoked potentials and neuronal activity, electrophysiological studies have been made on tecto-thalamo-cortical tract in rats. The existence of a system of efferent projections in the superficial, visual layers of the superior colliculi was shown which are diffusely present in the nucleus lateralis posterior (n. LP), indicating low level of morpho-functional organization of this region of the dorsal thalamus in rats. In response to electrical stimulation of the n. LP, in laterocaudal parts of the visual system (fields 17 and 18a of the cortex) the evoked potentials of primary-negative polarity were observed which are associated mainly with the superficial (I--IV) cortical layers. Predominant representation of tecto-thalamo-cortical system in the laterocaudal visual area of the cortex indicates the tendency to separate representation (with respect to cortical areas and cortical layers) of retino-geniculate and retino-tecal visual systems in rats.
通过记录诱发电位和神经元活动，对大鼠的顶盖-丘脑-皮质束进行了电生理研究。结果表明，在大鼠上丘的浅表视觉层中存在一个传出投射系统，该系统广泛分布于丘脑后外侧核（n. LP），这表明大鼠背侧丘脑该区域的形态功能组织水平较低。在对丘脑后外侧核进行电刺激时，在视觉系统的后尾侧部分（皮质的17区和18a区）观察到了主要与皮质浅表（I-IV）层相关的原发性负极性诱发电位。顶盖-丘脑-皮质系统在皮质后尾侧视觉区域的主要表现表明，大鼠视网膜-膝状体和视网膜-顶盖视觉系统在（相对于皮质区域和皮质层）代表性上存在分离的趋势。
