In unanesthetized immobilized spiny dogfish sharks, functional organization of the forebrain afferent projections was studied with the aid of evoked potentials (EPs) and neuronal responses to adequate stimulation of the eye with light and to electric stimulation of the optic nerve. The forebrain spontaneous unit activity (from 0.1 to 2.8 Hz) changed in response to the optic nerve electric stimulation with latency varying from 58 to 280 msec. Two foci of maximum unit activity were found at the depth of the visual area: at the levels from 850 to 1050 microns and from 1400 to 1600 microns from the forebrain surface. Histogram analysis of the data obtained showed that the main components of EPs reflected postsynaptic processes occurring in the dendrites of the forebrain visual area.
在未麻醉的固定刺鲨中，借助诱发电位（EPs）以及对眼睛进行光刺激和对视神经进行电刺激时神经元的反应，研究了前脑传入投射的功能组织。前脑自发单位活动（0.1至2.8赫兹）在对视神经进行电刺激时发生变化，潜伏期从58至280毫秒不等。在视觉区域深度发现了两个单位活动最大值的焦点：在前脑表面850至1050微米以及1400至1600微米的水平处。对所得数据的直方图分析表明，诱发电位的主要成分反映了前脑视觉区域树突中发生的突触后过程。
