It has been widely reported that both grating acuity and orientation discrimination show meridional variations: performance is better for targets oriented horizontally or vertically than for those with oblique orientations. In spite of such similarities, we now present both behavioral and psychophysical evidence from cats and humans to show that grating acuity and orientation discrimination depend upon different neuronal mechanisms.
已有广泛报道称，光栅敏锐度和方向辨别能力均呈现子午线变化：水平或垂直方向的目标表现优于倾斜方向的目标。尽管存在这些相似之处，但我们现在展示来自猫和人类的行为学和心理物理学证据，以表明光栅敏锐度和方向辨别依赖于不同的神经元机制。
