VEPs were recorded using 5.0 c/deg square wave gratings presented at vertical and oblique (45 deg) orientations and phase-alternated at two rates, 6 alternations/sec and 12 alternations/sec. In agreement with previous reports, VEP amplitude was smaller for obliquely oriented gratings than for vertically oriented gratings at both alternation rates. Unlike previous studies, however, the authors found that VEP latency was longer for obliquely oriented gratings at the slower (6/sec) alternation rate.
使用5.0 c/deg的方波光栅记录视觉诱发电位（VEPs），光栅呈现垂直和倾斜（45度）方向，并以两种频率进行相位交替，即6次/秒和12次/秒。与先前的报告一致，在两种交替频率下，倾斜方向光栅的VEP振幅均小于垂直方向光栅的VEP振幅。然而，与先前的研究不同，作者发现，在较慢的（6次/秒）交替频率下，倾斜方向光栅的VEP潜伏期更长。
