The Westheimer function in human cone vision was measured in normal observers under dichoptic conditions and in observers with naturally acquired amblyopia. Results show interocular transfer of both desensitization and sensitization under either "sustained" or "transient" stimulus conditions if binocular rivalry is eliminated. The spatial sensitization branches of the amblyopic functions are considerably broadened as compared with those of the non-amblyopic function. Our results are consistent with cortical components for the Westheimer function which probably reflect the behavior of cortical spatial filters.
在双眼分别接受刺激的条件下,对正常观察者以及自然形成弱视的观察者测量了人视锥细胞视觉中的韦斯特海默函数。结果表明,如果消除双眼竞争,在“持续”或“瞬态”刺激条件下,脱敏和敏化都会发生双眼间传递。与非弱视功能相比,弱视功能的空间敏化分支显著变宽。我们的结果与韦斯特海默函数的皮质成分一致,这可能反映了皮质空间滤波器的行为。
