Buddhism and the brain is a hot topic these days. Here's a recent BBC News report on meditation and the brains of Buddhist monks:
Dr Josipovic's research is part of a larger effort better to understand what scientists have dubbed the default network in the brain.
He says the brain appears to be organised into two networks: the extrinsic network and the intrinsic, or default, network.
The extrinsic portion of the brain becomes active when individuals are focused on external tasks, like playing sports or pouring a cup of coffee.
The default network churns when people reflect on matters that involve themselves and their emotions.
But the networks are rarely fully active at the same time. And like a seesaw, when one rises, the other one dips down.
This neural set-up allows individuals to concentrate more easily on one task at any given time, without being consumed by distractions like daydreaming.
"What we're trying to do is basically track the changes in the networks in the brain as the person shifts between these modes of attention," Dr Josipovic says.
Dr Josipovic has found that some Buddhist monks and other experienced meditators have the ability to keep both neural networks active at the same time during meditation - that is to say, they have found a way to lift both sides of the seesaw simultaneously.
And Dr Josipovic believes this ability to churn both the internal and external networks in the brain concurrently may lead the monks to experience a harmonious feeling of oneness with their environment.
