University students who were practicing the Transcendental Meditation and TM-Sidhi programs increased significantly on intelligence in contrast to control students. Reference: Personality and Individual Differences 12: 1105–1116, 1991.
University students who learned the Transcendental Meditation program showed after 40 days improved clustering in short-term memory, indicating increased organization of the thinking process, in comparison to randomly assigned controls who sat with closed eyes twice daily.

During the Transcendental Meditation program, early (sensory) components of the brain’s response to somatosensory stimuli are more widely distributed across the cortex, indicating greater participation of the whole brain in the response to a stimulus. Reference: Human Physiology 25: 171–180, 1999.
During the Transcendental Meditation technique individuals often report the subjective experience of Transcendental Consciousness or pure consciousness, the state of least excitation of consciousness. This study found that many experiences of pure consciousness were associated with periods of natural respiratory suspension, and that during these respiratory suspension periods individuals displayed higher mean EEG coherence over all frequencies and brain areas, in contrast to control periods where subjects voluntarily held their breath.
