Rj. Veldhuizen et al., SEX-DIFFERENCES IN AGE REGRESSION PARAMETERS OF HEALTHY ADULTS-NORMATIVE DATA AND PRACTICAL IMPLICATIONS, Electroencephalography and clinical neurophysiology, 86(6), 1993, pp. 377-384
After appropriate transformations age regression parameters for relati
ve band power values were determined in two groups of normal subjects
(94 men and 80 women) between 20 and 70 years of age. Four homologous
bipolar derivations over each hemisphere were considered. For most reg
ression equations significant sex differences were found for the inter
cept values; a sex difference for the regression coefficient was only
present for the temporal theta power. The use of patient and control g
roups composed solely of subjects of the same sex can be indicated whe
n studying groups of subjects with minor qEEG disturbances, an example
of which is given.
