What happens in the brain during altered states?
Short Answer
Altered states involve changes in neural network connectivity, neurotransmitter activity, and brainwave patterns that shift normal information processing and conscious awareness.
Why This Matters
These neurological shifts occur because psychoactive substances, meditation, or other triggers disrupt the brain's default mode network—the system responsible for self-referential thinking and maintaining ordinary awareness. This disruption leads to increased connectivity between normally separate brain regions, resulting in novel patterns of neural communication. The changes demonstrate how consciousness emerges from specific neural configurations that can be systematically modified.
Where This Changes
The intensity and type of neural changes vary significantly based on the method of induction, individual brain chemistry, and environmental factors. Some altered states produce minimal disruption while others create profound reorganization of neural activity.
