| 摘 要： | 根据心理物理实验和电生理实验的结果，选用对非零视差有选择性反应的视差敏感复杂细胞来检测视差信息，并把所提取的视差信息直接投射到聚散式眼动细胞（ｖｅｒｇｅｎｃｅｃｅｌ）以控制聚散式眼动。同时，综合考虑了复杂细胞编码范围的限制、近细胞和远细胞的相位关系以及跳跃式眼动后增强效应（ｐｏｓｔ－ｓａｃｃａｄｉｃｅｎｈａｎｃｅｍｅｎｔ）等因素。得到的模拟结果与心理物理实验结果定性地符合

| Abstract: | Based on electrophysiological and psychophysical experiment results, disparity sensitive complex cells which respond selectively to none-zero disparities are used to detect disparity information, which in turn are sent directly to vergence cells to control vergence eye movement. Various factors such as the limitation of the coding range of complex cells, the phase relationship between far cells and near cells and the effect of post-saccadic enhancement are also considered. The simulation results are consistent with those of psychophysical experiments qualitatively. |
