Abstract
Gamma-band activity, as examined by Pulvermueller et al.
(1994) is not necessarily a genuine and independent phenomenon but
may be an epiphenomenon of activity changes in lower frequency
bands. Recent experiments have shown a strong contribution of
harmonics of alpha activity to activity in the beta and gamma
ranges. The target article and the response to the commentary of
Mueller & Jokeit (1994) do not present enough evidence to
invalidate the hypothesis that the observed gamma-band effects are
merely due to changes in alpha power.
