Abstract

In adult cats one eye was surgically immobilized by sectioning the eye muscles, or inverted by 180 degrees rotation, or pattern-deprived by suturing the eyelids for 1-12 weeks. Orientation and direction selectivity of cortical cells and binocularity were preserved; no shift in the ocular dominance distribution toward either eye was found. The visual cortex of adult cats is therefore not susceptible to changes in the content of the visual input.

摘要

在成年猫中，通过切断眼肌使一只眼睛手术固定，或通过180度旋转使其倒置，或通过缝合眼睑1至12周使其图案剥夺。皮层细胞的方向和方向选择性以及双眼视功能得以保留；未发现眼优势分布向任何一只眼睛偏移。因此，成年猫的视觉皮层不易受到视觉输入内容变化的影响。
