A Directionally Selective Binocular Unit in the Midbrain Tegmentum of Tribolodon hakonensis(Physiology)

元データ 社団法人日本動物学会

概要

Directionally selective visual units were recorded in and around the mesencephalic posterior commissure in Japanese dace (Tribolodon hakonensis) during stimulation by a rotating striped drum. Spontaneous discharge rates of the units were increased or decreased depending on the direction of rotation of the drum. The units had movement-sensitive, binocularly-driven receptive fields with horizontal extents of 240°. The relation between the properties of the directionally selective units and optokinetic responses induced by the same stimuli is discussed.
