用细胞内记录和染色技术，在离体眼杯中研究了海龟视网膜的方向选择性（DS）神经节细胞和其他神经节细胞。DS神经节细胞响应移动光栅周期性，去极化突触电位在两个首选和零方向。虽然去极化通常是更大的首选方向比零方向，在少数细胞的尖峰放电的方向，但去极化。如果使用不适当的场大小或光栅空间频率，方向性可能消失。
Directionally selective (DS) and other ganglion cells of the turtle retina were studied in in vitro eyecup preparations by using intracellular recording and staining techniques. DS ganglion cells responded to moving gratings with periodic, depolarizing synaptic potentials in both preferred and null directions. Although depolarizations were usually larger in the preferred than in the null directions, in a few cells spike discharges were directional but depolarizations were not. Directionality could disappear if inappropriate field sizes or grating spatial frequencies were used.
