Summary
Practicing Autogenic Training may reduce overall brain activation. Long-term practitioners show altered cerebral blood flow, with increased flow in body-related areas and decreased flow in attention and autonomic regions.
Area of Science:
- Neuroscience
- Psychophysiology
Context:
- Investigating the long-term effects of Autogenic Training on brain activity.
- Utilizing 133-Xenon inhalation method for cerebral blood flow measurement.
Purpose:
- To determine if Autogenic Training alters the typical hyperfrontal pattern of hemispheric blood flow.
- To examine regional cerebral blood flow changes associated with Autogenic Training practice.
Summary:
- Healthy men with 6+ months of Autogenic Training did not exhibit the expected hyperfrontal pattern.
- Autogenic Training practice correlated with increased blood flow in the Rolandic area (body schema) and decreased flow in acoustical attention and autonomic function regions.
- Lower resting left hemispheric cerebral blood flow was observed, with discussion on relative left-hemisphere activation during training.
Impact:
- Suggests a potential long-term decrease in overall brain activation levels due to Autogenic Training.
- Highlights specific regional brain blood flow modifications linked to Autogenic Training, impacting body schema, attention, and autonomic control.
- Provides insights into the neurophysiological underpinnings of Autogenic Training and its effects on hemispheric lateralization.
