Washington: Transcendental Meditation technique has the ability to activate the default mode network-a suggested natural 'ground state' of the brain, according to a new
EEG study. The three-month randomised control study was conducted on college students
at American University. The study found that the TM technique produces a unique
state of "restful alertness," as seen in the markedly higher alpha power in the
frontal cortex and lower beta and gamma waves in the same frontal areas during
TM practice. It creates greater alpha coherence between the left and right hemispheres
of the brain suggesting the brain is working as a whole. The technique also enhances
an individual's sense of "self" by activating what neuroscientists call the "default
mode network" in the brain. The brain's "default mode network" is considered the
natural ground state of the brain, glimpsed by neuroscientists during eyes-closed
rest but more fully activated during Transcendental Meditation practice. The study
has been published in a special issue of Cognitive Processing dedicated to the
Neuroscience of Meditation and Consciousness. |
