Spectral analysis of alpha rhythm during Schultz's autogenic training. A tentative approach to rapid visualization.
The records from experimental sessions including autogenic standard exercises and other conscious states, in two long-term trainees, were treated by using a frequency analysis programme. Starting from a synoptic reduced representation of the data and selecting sequences for the building of histograms of averaged energy levels in limited frequency bands, the authors describe the progressive spread of a dominant alpha band all over the scalp during autogenic training.
