| 摘 要： | 利用NICOLET CA—1000型原黑—白棋盘格图形信号,通过增设工作类别开关和彩色棋盘格图形选择开关,研制成黑—白和彩色棋盘格图形兼容的刺激器.对正常人做了初步VEP 测试。因彩色呈棋盘格图形,使诱发电位有较稳定(较彩色闪烁刺激)的波形,类似黑—白盘棋格反转视诱发电位的波形,又含有较多颜色影响的信息.

| Abstract: | With the addition of working and color seleotion switches to NTCOLETCA-1000VEP black-white stimulus,A compatible visual stimulator with3 kinds of color checkerboard patterns,including black-red,black-blueand black-white,was developed.Preliminary VEP tests were done innormal subjets.As compared to color flicker stimulus,VEP waveformswere more stable under the color checkerboard stimulus.The VEPwaveforms elicited by the new system resembled those of black-whitecheckerboard reversal and had more color effect in the information. |
