Immunocytochemical and histochemical localization of nitric oxide synthase in the turtle retina.

abstract：:Although galvanic vestibular stimulation (GVS) is known to affect the speed and accuracy of visual judgments, the underlying electrophysiological response has not been explored. In the present study, we therefore investigated the effect of GVS on the N170 event-related potential, a marker commonly associated with earl...
