| Abstract: | dentified 3 EEG patterns during the performance of hathayogic exercises by 3 healthy males with long-term experience: (1) a 'wicket' wave-form rhythm (Xi rhythm), (2) a 26-33 Hz sinusoidal rhythm, and (3) high-amplitude paroxysmal activity. The findings confirm the hypothesis that these exercises provoke EEG changes around the somatosensory and parietal-cortical areas of the brain and that they can occur at the same time as affective arousal. (PsycINFO Database Record (c) 2002 APA, all rights reserved); Concurrent with the performance of hathayogic exercises such as Nauli, Bhastrika and Suryabhedana, three characteristic EEG patterns were identified: a "wicket" rhythm at a frequency wave of 12 to 17 Hz, recordable from para-Rolandic areas, which we have called Xi rhythm; a 26-33 Hz sinusoidal activity, confined to the mid-sagittal parietooccipital region; and paroxysmal activity localized in the lateral boundaries of parieto-temporo-occipital regions, bilaterally. - The expectation that hathayogic exercises would affect the electrical activity of circumscribed, relatively well defined areas of the brain was based on the fact that these exercises imply a strong stimulation of somatic and splanchnic receptors, the afferent impulses of which are fed into specific cortical representation areas localized for the most part around central and anterior parietal areas. / Identified 3 EEG patterns during the performance of hathayogic exercises by 3 healthy males with long-term experience: (1) a "wicket" wave-form rhythm (Xi rhythm), (2) a 26â€_Äì33 Hz sinusoidal rhythm, and (3) high-amplitude paroxysmal activity.
