Do altered states increase neural plasticity?
Short Answer
Research indicates altered states of consciousness can enhance neural plasticity by promoting neurogenesis, increasing BDNF levels, and facilitating new synaptic connections.
Why This Matters
Altered states appear to reduce activity in the default mode network while increasing neurotropic factors like BDNF (brain-derived neurotrophic factor), which supports the growth of new neurons and synapses. This neurochemical environment facilitates learning and memory consolidation because it creates optimal conditions for neural rewiring. Studies of meditation, psychedelics, and sensory deprivation demonstrate measurable increases in dendritic branching and synaptic density following these experiences.
Where This Changes
The plasticity enhancement varies significantly based on the type, duration, and intensity of the altered state. Some states may temporarily reduce plasticity during the acute phase while increasing it during recovery periods.
