In frogs, multi-unit receptive fields (MURF) of rostral binocular tectal points (BTP) show a crossed disparity when mapped at a distance equal to the perimeter radius (i.e., 33 cm). The shape of the spatial surface where MURF of all BTP are in-register is investigated in two planes: (a) in the longitudinal plane, the locus of superimposition is a circumference passing through both eyes; (b) in the vertical plane, it corresponds to a straight line tilted towards the animal's head. This surface can be defined as the frog's horopter surface since it represents the spatial locus where objects can simultaneously stimulate corresponding retinal areas. Behavioural and electrophysiological correlations are discussed.
在青蛙中，当在等于周边半径（即33厘米）的距离处进行映射时，吻侧双眼视顶盖点（BTP）的多单位感受野（MURF）呈现交叉视差。在两个平面上研究了所有BTP的MURF对齐的空间表面的形状：（a）在纵向平面中，叠加轨迹是一个穿过双眼的圆周；（b）在垂直平面中，它对应于一条向动物头部倾斜的直线。这个表面可以被定义为青蛙的双眼单视界表面，因为它代表了物体可以同时刺激相应视网膜区域的空间轨迹。文中还讨论了行为和电生理相关性。
