Wilson和Humanski（1993）最近报道了适应低时间频率正弦波光栅对短暂呈现的测试刺激产生的阈值升高很小的证据。我们假设短暂刺激可以被瞬态通道检测到，该瞬态通道受低时间频率适应模式的影响最小。因此，我们测量了适应的影响，简要介绍了测试刺激的适应时间频率范围更广，结果表明，适应可能会产生阈值升高的简要介绍的刺激，高比低的时间频率适应模式的阈值升高更大，这些结果是一致的假设，即简要介绍的刺激被检测到的瞬态通道。
Wilson and Humanski (1993) have recently reported evidence that adapting to low temporal frequency sinewave gratings yields little threshold elevation for briefly presented test stimuli, We postulated that brief stimuli may be detected by a transient channel which would be minimally affected by a low temporal frequency adapting pattern. We therefore measured the effect of adaptation on briefly presented test stimuli for a wider range of adapting temporal frequencies, The results indicate that adaptation may yield threshold elevation for briefly presented stimuli and that threshold elevation is greater for high than low temporal frequency adapting patterns, These results are consistent with the hypothesis that briefly presented stimuli are detected by a transient channel.
