  • There are two types of meditation techniques- Concentrative and Nondirective
  • A team of Norwegian researchers studied fourteen people’s meditation by MRI scan
  • They have found out how the brain operates in different techniques

July 17, 2017: The Royal Norwegian Embassy in New Delhi mentioned about the latest research in Oslo. MRI scans of 14 people were studied in three different states- Resting, Nondirective meditation and Concentrative meditation. The research sought to find out how meditation affects the brain activity.

Nondirective and Concentrative are the two main groups of meditation techniques. The concentrative meditation, as the name suggests, is when you suppress all other thoughts by focusing intensely on one specific thought. For many, that one specific thought is breathing. In Nondirective meditation, your mind is allowed to wander to all sorts of places beyond reality while the body still balances and focuses on breathing, mentioned ANI report.

Researchers from the University of Oslo, University of Sydney, and Norwegian University of Science and Technology studied to brain scans to determine how the brain was functioning under different states.

The part of the brain responsible for self-thoughts and feelings was more active in the nondirective method as compared to the state of resting. However, in concentrative meditation, the brain activity was the same as resting. Jian Xu, one of the researchers, observed how “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.”

The research concludes that there is more room for thoughts and emotions to process in nondirective meditation.

Exposure To High Levels of Air Pollution May Lead To Changes in Children’s Brain Structure

Previous studies of traffic-related air pollution suggest that it contributes to neurodegenerative diseases and neurodevelopmental disorders

Exposure to high levels of traffic-related air pollution at age 1 may lead to structural changes in the brain at the age of 12 which can influence the development of various physical and mental processes, warns a study.

The researchers found that children with higher levels of air pollution exposure at birth had reductions at age 12 in gray matter volume and cortical thickness as compared to children with lower levels of exposure. Gray matter includes regions of the brain involved in motor control as well as sensory perception, such as seeing and hearing. Cortical thickness reflects the outer gray matter depth.

The study, published online in the journal PLOS One, found that specific regions in the frontal and parietal lobes and the cerebellum were affected with decreases on the order of three to four per cent. “The results of this study, though exploratory, suggest that where you live and the air you breathe can affect how your brain develops,” said lead author of the study Travis Beckwith, PhD, a research fellow at Cincinnati Children’s Hospital Medical Center in the US.

“While the percentage of loss is far less than what might be seen in a degenerative disease state, this loss may be enough to influence the development of various physical and mental processes,” Beckwith said. For the study, the researchers used magnetic resonance imaging to obtain anatomical brain images from 147 kids.

These children are a subset of the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS), which recruited volunteers prior to the age of six months to examine early childhood exposure to traffic-related air pollution and health outcomes.

The volunteers in the CCAAPS had either high or low levels of pollution exposure during their first year of life. The researchers estimated exposure using an air sampling network of 27 sites in the Cincinnati area, and 24/7 sampling was conducted simultaneously at four or five sites over different seasons.
