Brain Imaging Parses Transcendental Meditation Practice

New research explains differences and dispels misconceptions regarding Transcendental Meditation and other meditation practices.

As published in the journal Brain and Cognition, investigators contend that subjective experiences and cortical activation patterns help to distinguish the Transcendental Meditation technique.

“Transcendental Meditation uses a mantra, and for this reason some researchers maintain that it involves focused attention and controlling the mind,” said lead author Fred Travis, Ph.D. “Those who practice Transcendental Meditation know this is not the case. This study supports their experience that Transcendental Meditation is easy to learn and effortless to practice.”

Investigators suggest that self-reports and brain patterns support the unique nature of a Transcendental Meditation practice.

This study involved 87 students at Maharishi University of Management in Fairfield, Iowa, who had been practicing the Transcendental Meditation technique from one month to five years.

Researchers investigated experiences and brain patterns of students as they rested with eyes closed, during Transcendental Meditation practice, and while engaging in a challenging computer task.

“There are two key findings from this study,” said Travis. “First, individuals practicing Transcendental Meditation for just one month reported the same frequency of ‘transcendental consciousness’ experiences during their practice as individuals meditating for five years.

“This supports the understanding that Transcendental Meditation uses the natural tendency of the mind to transcend — to move from active thinking to deep, inner silence. Extensive practice doesn’t make a natural process go any better.”

The second finding deals with activity in the “default mode network,” which is a large-scale brain network involving areas in the front and back of the brain that are active during internal thinking and self-referential activity, such as creating an autobiographical story.

Default mode network activity is high when a person just sits with his or her eyes closed, and low when one opens one’s eyes and begins to interact with the world.

The study reports that activity in the default mode network remained high during Transcendental Meditation practice. Activity in the default mode network is reported to go down in all other types of meditation since they involve focus and control of the mind.

“Deactivation of the default mode network indicates how much effort we are using,” Travis said.

“While people may not have had the experience of effortless transcending and so do not know what it feels like to transcend, they can now see the objective high activation in the default mode network, and see that something different is happening during Transcendental Meditation practice.”

Researchers note that Transcendental Meditation is different from resting with one’s eyes closed.

The study found that the default mode network was as high during Transcendental Meditation practice as during eyes-closed rest.

“This is an important finding, since eyes-closed rest is usually used as the benchmark for default mode network activity,” Travis said. However, he found two important differences when comparing the brain states during Transcendental Meditation and eyes-closed rest.

Eyes-closed rest had more beta brain waves in areas of the brain associated with memory and motor aspects of speech production.

“This could reflect the mental chatter that goes on when one’s eyes are closed,” Travis said.

Transcendental Meditation had more theta brain waves in orbitofrontal areas associated with reward anticipation. The meditators’ attention may have been absorbed in the inner march of the mind, attracted by the increasing “charm” of finer levels of mental functioning.

This process did not involve effort or control of the mind since default mode network activity was high.

These differences — the activity in the default mode network, as well as the fact that the frequency of transcending is the same regardless of how long one has been practicing — contrast Transcendental Meditation with other meditation practices.

“It’s a critical point,” Travis said. “Researchers, commentators, and popular media often lump meditation practices together.

“This distorts understanding the benefits of different meditations and confounds applying these approaches to different subject populations.”
