Your brain on meditation

Call it what you like, meditation is more than just a way to calm our thoughts and lower stress levels. Our brains process more thoughts and feelings during meditation than when we are simply relaxing.

There are countless ways of meditating, but the purpose behind them all remains basically the same: more peace, less stress, better concentration, greater self-awareness and better processing of thoughts and feelings.

But which of these techniques should a poor stressed-out wretch choose? What does the research say? Very little – at least until now.

A team of researchers at the Norwegian University of Science and Technology (NTNU), the University of Oslo and the University of Sydney is now working to determine how the brain works during different kinds of meditation.

Their most recent results appear in the journal Frontiers in Human Neuroscience.

Directive versus non-directive

Different meditation techniques can actually be divided into two main groups. One type is concentrative meditation, where the meditating person focuses attention on his or her breathing or on specific thoughts, and in doing so, suppresses other thoughts.

The other type may be called nondirective meditation, where the person who is meditating effortlessly focuses on his or her breathing or on a meditation sound, but beyond that the mind is allowed to wander as it pleases. Some modern meditation methods are of this nondirective kind.

Wandering free

For this study 14 people who had extensive experience with the non-directive Norwegian technique Acem meditation were assessed using an MRI machine. In addition to simple resting, they undertook two different mental meditation activities, nondirective meditation and a more concentrative meditation task.

It was important to test people who were experienced in meditation because it meant fewer misunderstandings about what the subjects should actually be doing while they lay in the MRI machine.

Result;s showed that nondirective meditation led to higher activity than during rest in the part of the brain dedicated to processing self-related thoughts and feelings. When test subjects performed concentrative meditation, the activity in this part of the brain was almost the same as when they were just resting.

“I was surprised that the activity of the brain was greatest when the person’s thoughts wandered freely on their own, rather than when the brain worked to be more strongly focused,” said researcher Jian Xu, who is a physician at St. Olavs Hospital in Trondheim, Norway and a researcher at the Department of Circulation and Medical Imaging at NTNU.

Processing thoughts & feelings

When the study participants stopped doing a specific task and were not really doing anything special, there was an increase in activity in the area of the brain where we process thoughts and feelings – which can be described as a kind of resting network.

It was this area that was most active during nondirective meditation.

“This area of the brain has its highest activity when we rest. It represents a kind of basic operating system, a resting network that takes over when external tasks do not require our attention. It is remarkable that a mental task like nondirective meditation results in even higher activity in this network than regular rest,” says Svend Davanger, a neuroscientist at the University of Oslo, and co-author of the study.

“The study indicates that nondirective meditation allows for more room to process memories and emotions than during concentrated meditation,” he adds.
