Peer-Reviewed Publication Yale University image: Experienced meditators seem to switch off areas of the brain associated with wandering thoughts, anxiety and some psychiatric disorders such as schizophrenia.
Researchers used fMRI scans to determine how the brains of meditators differed from subjects who were not meditating. The areas shaded in blue highlight areas of decreased activity in the brains of meditators.

Meditation's ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. Brewer, assistant professor of psychiatry and lead author of the study published the week of Nov.
Understanding how meditation works will aid investigation into a host of diseases, he said. Can psoriasis affect the brain Yale team conducted functional magnetic resonance imaging scans on both experienced and novice meditators as they practiced three different meditation techniques.
They found that experienced meditators had decreased activity in areas of the brain called the default mode network, which has been implicated in lapses of attention and disorders such as anxiety, attention deficit and 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. 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 can psoriasis affect the brain present-centered awareness, and less "self"-centered, say the researchers.
This gives us some nice cues as to the neural mechanisms of how it might be working clinically. Worhunsky, Jeremy R. Gray and Hedy Kober. The research was funded by the National Institutes vörös sima folt a karon Health and U. Media Contact.
