Abstract

Reaction time distributions (RTDs) were determined in response to near-threshold increments of long duration. Stimulus parameters were selected to isolate the chromatic and achromatic systems. The RTDs for the achromatic system peak sooner and are more narrow than those obtained for the chromatic system. These results are analyzed in terms of the neural discharge pattern of parvo and magno pathways.

摘要

针对长时间接近阈值的增量测定了反应时间分布（RTDs）。选择刺激参数以分离彩色和非彩色系统。非彩色系统的RTDs比彩色系统的RTDs更早达到峰值且更窄。根据小细胞和大细胞通路的神经放电模式对这些结果进行了分析。
