利用VEP测量视觉系统红,绿通道的反应时间差

本文应用彩色诱发电位（ＣＯＬＯＲ ＶＥＰ）在专门研制的双计算机互连系统，对人眼视觉系统中颜色通道的时间响应特性作初步研究，实验发现，在等主观亮度而颜色不同的棋盘格图形翻转刺激下ＶＥＰ中Ｎ１波的伏期因刺激颜色不同而不同。对实验结果的数据做统计的分析得出人眼颜色并行通道对三基色的响应有明显的差别，绿通道快于红通道。此结果１９９０年ＳＳ．Ｍ．Ｃｏｕｒｔｎｅｙａｎｄ Ｇ．Ｂｕｃｈｓｈａｕｍ提出的视觉颜色的

Measurement of the Temporal Response for R and G pathway by Visual Evoked Potential

Using the color pattern reversal visual evoked POtential (color VEP), we studied the temPOralproperties of man's visual color pathway by means of the special two connected computers system['J. The resultsshowed:under the condition of equal subjective brightness and the stimulation of turning different color chessboardpattern,the temporal response of NI wave of the VEP is different because of the color stimulation. Statistitcal analyses of experiment data show that there are significant differences between three elementary color temporal responses within visual color parallel pathways. The green pathway(G-pathway) is faster than Red pathway (R-pathway). These results corresPOnd with the visual color pathway modelLZJ presented by S. M. Courtney and G.Buchshaum in 1990.
