Date of correction: February 24, 2009 Reason for correction: - Correction: ABSTRACT Details: Wrong : A previously reported measure of amplitude variability in the wakeful EEG (the coefficient of variation, CV) using a 20 second time base and a recently developed temporal measure (the coefficient of temporal variability (CVT) using a much shorter time base, were calculated from EEG records of 50 normal males) before and after a cold pressor stress of one minute. Pre and post conditions were analyzed so that the correlations for each measure of EEG variability could be compared and the association of each could be evaluated under each condition. While both the CV and CVT of these two different series were reliable at the 0.05 level; the CVT was significantly more reliable than the CV. The two measures were not significantly related to each other. It was suggested that the more descriptive and reliable patterning of the CVT series be used to explore the relationship of EEG frequency to EEG amplitude variability and that this measure of EEG variation be compared to similar measure-ments of variation in other physiological systems that are known to have behavioral correlates.
