Can altered states dull sensation?
Short Answer
Altered states can significantly dull sensation by disrupting normal sensory processing pathways in the brain, reducing awareness of physical stimuli like pain, touch, and temperature.
Why This Matters
This sensory dulling occurs because altered states modify neurotransmitter activity and alter communication between brain regions responsible for processing sensory input. Substances like anesthetics, psychedelics, and meditation states can suppress activity in the thalamus and somatosensory cortex, which normally relay and interpret sensory signals. This demonstrates how consciousness and sensory perception are interconnected processes that can be selectively modified.
Where This Changes
The degree of sensory dulling varies based on the type and intensity of the altered state. Some states enhance certain sensations while dulling others, and individual neurochemistry affects sensitivity to these changes.
