Spatial profile of a projection from retina to the suprachiasmatic nucleus (SCN) was studied by electrophysiological method. Stimulation of contralateral optic nerve evoked the fast positive and late large negative waves in only the ventrolateral but not the dorsolateral parts of the posterior SCN. This result, in agreement with anatomical evidence suggests that the late negative wave is due to excitatory synaptic potential in the SCN and has a role for elevating the neuronal activity in the ventrolateral part of the posterior SCN daytime.
采用电生理学方法研究了视网膜至视交叉上核（SCN）投射的空间分布。刺激对侧视神经仅在后SCN的腹外侧而非背外侧部分诱发快速正波和晚期大负波。这一结果与解剖学证据一致，表明晚期负波是由于SCN中的兴奋性突触电位所致，并且在白天对提高后SCN腹外侧部分的神经元活动起作用。
