The summing properties of the surround response mechanism of cat retinal ganglion cells were assessed by determining area-sensitivty and area-adaptation curves. The two curves were found to be similar for X and Y cells but for many Y cells adaptive sensitivity was found to be dependent upon the size of the test target. These results suggest that, for X cells, the retinal area over which the surround integrates signals and adaptation are spatially coextensive. Most Y cells appear to pool adaptive effects over a smaller region than they pool signals.
通过测定面积敏感性和面积适应曲线，评估了猫视网膜神经节细胞周围反应机制的总和特性。发现X细胞和Y细胞的这两条曲线相似，但对于许多Y细胞，发现适应性敏感性取决于测试目标的大小。这些结果表明，对于X细胞，周围整合信号和适应的视网膜区域在空间上是共延的。大多数Y细胞似乎在比它们汇集信号的区域更小的区域内汇集适应性效应。
