Effect of body position on bilateral EEG alterations and their relationship with autonomic nervous modulation in normal subjects

摘要: This study investigated the effect of body position on electroencephalogram (EEG) and autonomic nervous modulation, relationship between them using spectral analysis EEG heart rate variability (HRV). All healthy volunteers recruited had their electrocardiogram recorded for power analysis. We found that when changing from supine to upright, components below α band, such as δ θ bands, were significantly decreased while above β, γ ω increased in both scalps. Correlation showed rhythm scalps might be associated with control HR, β rhythms right scalp vagal left sympathetic modulation subject. Thus, some subject during positional change. There a mechanism located brain-stem which jointly controls influences activation.
