Abstract
We investigated the interaction of β-rhythm parameters with α and θ rhythms in a paradigm of cognitive set as a response on facial expression in 35 healthy adults. Data were analyzed by means of continuous wavelet transform on the basis of “maternal” complex Morlet-wavelet in a range of 1–35 Hz. Distribution cards of the values of the wavelet-transform coefficient (WLC) module characterizing potentials amplitude were analyzed. We used indicators of the mean and maximal WLC levels. A significant interaction between β2 and α rhythms at the mean WLC level at the stage of set formation was revealed in a group with rigid set, and a correlation coefficient was 0.57. The interaction between β2 and θ rhythms at the mean WLC level (correlation coefficient was 0.74) and WLC maximum (correlation coefficient was 0.8) at the same experimental stage in the group with the flexible set was found.
