Mapping the Mind

Scientists at the University of Pennsylvania have been studying changes within the brain during meditation to better understand the physical and tangible changes that take place during spiritual experiences.

The researchers studied a group of Tibetan Buddhist monks. The monks meditated for one hour and were asked to signal when they had reached a deep state of meditation. Radioactive dye was then released into their bloodstream to show which parts of the brain are most active during meditation.

The results showed increased activity in frontal parts of the brain, normally associated with deep concentration and decreased activity in the parietal lobe, associated with orientation and spatial awareness.

Dr Andrew Newberg, speaking on behalf of the team commented, "During meditation, people have a loss of the sense of self and frequently experience a sense of no space and time and that was exactly what we saw".

"I think we are poised at a wonderful time in our history to be able to explore religion and spirituality in a way which was never thought possible".

A previous study reported in December showed the healing properties of prayer and meditation and suggested controlled relaxation techniques can help reduce the risk of heart attack.

Paul O'Keeffe of Bromley Health Management commented, "This study supports what many of us already know; meditation is just about concentrating on yourself and closing off the world around you. At the lowest level, this just means taking a moment with your own thoughts. With practice or a little help, you can achieve greater control over your mind and body, which is why we see real health benefits from regular meditation".
