Imaging Shows How Meditation Tunes Out Some Brain Areas

Imaging Shows How Meditation Tunes Out Some Brain AreasA new brain imaging study suggests experienced meditators are able to switch off areas of the brain.

Yale researchers say the brain regions are associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia.

Experts have tied meditation’s focus on the present moment with increased happiness and other benefits. Understanding how meditation works will aid investigation into a host of diseases, said Judson A. Brewer, M.D., Ph.D., an assistant professor of psychiatry and lead author of the study.

The study will be published in the Proceedings of the National Academy of Sciences.

“Meditation has been shown to help in variety of health problems, such as helping people quit smoking, cope with cancer, and even prevent psoriasis,” Brewer said.

The Yale team conducted functional magnetic resonance imaging scans on both experienced and novice meditators as they practiced three different meditation techniques.

Investigators discovered experienced meditators had decreased activity in areas of the brain called the default mode network. This area has been implicated in lapses of attention and disorders such as anxiety, attention deficit hyperactivity disorder, and even the buildup of beta amyloid plaques in Alzheimer’s disease.

The decrease in activity in this network, consisting of the medial prefrontal and posterior cingulate cortex, was seen in experienced meditators regardless of the type of meditation they were doing.

The scans also showed that when the default mode network was active, brain regions associated with self-monitoring and cognitive control were co-activated in experienced meditators but not novices.

This may indicate that meditators are constantly monitoring and suppressing the emergence of “me” thoughts, or mind-wandering. In pathological forms, these states are associated with diseases such as autism and schizophrenia.

Researchers discovered the meditators did this both during meditation, and also when just resting — not being told to do anything in particular.

This may indicate that meditators have developed a “new” default mode in which there is more present-centered awareness, and less “self”-centered, say the researchers.

“Meditation’s ability to help people stay in the moment has been part of philosophical and contemplative practices for thousands of years,” Brewer said.

“Conversely, the hallmarks of many forms of mental illness is a preoccupation with one’s own thoughts, a condition meditation seems to affect. This gives us some nice cues as to the neural mechanisms of how it might be working clinically.”
