Ampl=amplitude, µV=micro volts, IT=implicit time, ms=milliseconds, SD=standard deviation Amplitudes lower than the mean −2 SD are considered pathologically reduced and are highlighted in bold and italics. Implicit times delayed more than the mean + 2SD are also considered pathological and highlighted in bold and italics.
