noticeably after just eight weeks of regular meditation. we've identified a very interesting effect we measure brain function that we know reflect concentration conscious concentration and. this function was significantly boosted after meditation therapy. close up. the researchers measured increased electrical activity in the cortex indicating changes have occurred deeper in the brain other processes such as c.t. scans have confirmed that changes. deep inside the brain neural pathways are reinforced in response to particular stimuli and new ones developed. where more neural capacity is needed more connections are forged.
