Abstract

Layer V pyramidal cells of the cat lateral suprasylvian visual areas project to the pontine nuclei. Although all 6 of the suprasylvian visual areas project to the pons, the densest projections are from 3 areas: anterior medial lateral suprasylvian (AMLS), posterior medial lateral suprasylvian (PMSL) and ventral lateral suprasylvian (VLS). The organization of the corticopontine pathway from one of these areas (PMLS) suggests a disproportionate representation of the peripheral visual fields. This pattern of projection would serve to de-emphasize the central visual field.

摘要

猫外侧上薛氏视觉区的第五层锥体细胞投射至脑桥核。尽管所有6个上薛氏视觉区均投射至脑桥,但投射最密集的是3个区域:前内侧外侧上薛氏区(AMLS)、后内侧外侧上薛氏区(PMSL)和腹外侧上薛氏区(VLS)。来自这些区域之一(PMLS)的皮质脑桥通路组织表明外周视野的表征不均衡。这种投射模式将有助于弱化中央视野。
