We have studied binocularity in Rana pipiens using optical, behavioral, and electrophysiological assays. The first two assays yielded a consistent picture of the size and shape of the area of uniocular visual field overlap, the potential binocular field. Potential binocular field has an extent of about 90 degrees on the horizontal in front of the frog, narrows to about 60 degrees above the frog's head, and continues to a point well behind the frog. This differs somewhat from a previous report (Fite, '73). Uniocular visual field extent on the horizontal is in excess of 225 degrees, permitting both a large binocular field and panoramic vision. The electrophysiological assay confirms the large uniocular visual field extent. It further shows that physiological binocularity closely reflects uniocular visual field overlap, in the sense that tectal loci representing positions in the potential binocular field, including those behind the frog's head, display convergent inputs from the two eyes.
我们使用光学、行为学和电生理学方法研究了豹蛙的双眼视觉。前两种方法得出了单眼视野重叠区域（即潜在双眼视野）大小和形状的一致图像。潜在双眼视野在青蛙前方水平方向上约有90度的范围，在青蛙头部上方变窄至约60度，并一直延伸到青蛙后方的一个点。这与之前的一份报告（Fite，1973年）略有不同。水平方向上的单眼视野范围超过225度，既允许有大的双眼视野，也允许有全景视觉。电生理学方法证实了单眼视野范围很大。它还进一步表明，生理上的双眼视觉紧密反映了单眼视野重叠，即代表潜在双眼视野中位置（包括青蛙头部后方的位置）的顶盖位点显示出来自双眼的汇聚输入。
