Interaction of delta, theta and alpha activity in schizophrenics, depressives and alcoholics

چکیده
Differences between EEG/MEG power spectra in different psychiatric disorders and controls have often been reported (overview Winterer and Herrmann, 1995; Tauscher, 1995). The present study examined the distribution of magnetic source activity in different frequency bands in schizophrenics, depressives, alcoholics and controls. In addition, for controls and schizophrenics correlations between minimumnorm-values over different regions and frequency bands were calculated.

Functional imaging of brain electrical activity was performed in 25 chronic medicated schizophrenics and 40 controls, analyzing the classical frequency bands (delta, theta, alpha, and beta) of 19-channel EEG during resting state to identify brain regions with deviant activity of different functional significances, using LORETA (Low Resolution Tomography) and SPM99 (Statistical Parametric Mappin...
متن کاملThe effects of acute, sub-chronic and chronic psychical stress on the brain electrical activity in male rats
Introduction: Stress is a main factor influencing brain functions as revealed by the electroencephalogram (EEG) recordings. Moreover, different stress durations seemingly cause perturbations in brain waves and lead to mental disorders. This study investigates the effects of acute, sub-chronic and chronic stress on EEG in rats. Methods: Twenty-eight Wistar adult male rats were randomly all...

At first, interested students were invited to participate in the research, and 30 of them were randomly selected and selected from delta, theta,...
متن کاملBrain Wave Patterns in Patients with Chronic Low Back Pain: A Case-Control Study
Introduction: Research evidence indicates that maladaptive reorganization of the brain plays a critical role in amplifying pain experiences and pain chronification; there is, however, no clear evidence of change in brain wave activity among patients with chronic low back pain (CLBP). The objective of this study was to assess brain wave activity in patients with CLBP, compared to healthy control...
