Altered States of Awareness

Altered States of Awareness

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain that...

Summary

Meditation practices like dharana and ekagrata delay auditory information transmission, while dhyana meditation shows no such effect. This suggests dhyana may preserve neural processing efficiency in the auditory pathway.

Area of Science:

Neuroscience
Cognitive Science
Psychology

Background:

Mental repetition of "OM" influences middle latency auditory-evoked potentials.
This suggests facilitation of neural activity at mesencephalic or diencephalic levels.

Purpose of the Study:

To investigate brainstem auditory-evoked potentials (BAEP) during two distinct meditation states: dharana and dhyana.
To compare BAEP changes across meditation states and control conditions.

Main Methods:

Thirty experienced "OM" meditators (20-55 years) participated.
BAEP were recorded during four sessions: dharana (focused "OM"), dhyana (effortless "OM"), ekagrata (lecture), and cancalata (non-targeted thinking).
Each session included pre, during, and post-recording phases.

Main Results:

Wave V peak latency significantly increased during cancalata, ekagrata, and dharana sessions.
No significant change in wave V peak latency was observed during the dhyana meditation session.

Conclusions:

Auditory information transmission is delayed along the auditory pathway during cancalata, ekagrata, and dharana.
Dhyana meditation does not alter auditory information transmission, potentially indicating preserved neural processing at the inferior collicular level (wave V).
