An excellent summary of ancient and contemporary information on the subject can be found in Michael Murphy's landmark book …show more content…

Changes in Brainwaves and Enhanced Perception
It should come as no surprise that among the well-documented effects of meditation is the alteration of brain-wave patterns. Dozens of studies have shown an increase in alpha rhythms, which are correlated with a state of relaxed alertness. In addition, numerous studies have shown enhanced synchronization of alpha rhythms among four regions of the brainÑright, left, front, and back. This may be an indication of increased coherence of brain-wave activity.4
Some researchers have demonstrated positive effects of meditation on mind-body coordination, exploring this area by measuring such parameters as visual sensitivity to light flashes,5 response to auditory stimuli,6 and ability to remember and discriminate musical tones.7 There are also indications that during meditation the function of the right hemisphere of the brain (generally correlated with creativity and imagination) is enhanced, while that of the left hemisphere (generally correlated with linear, intellectual thought) is inhibited.8
Despite the encouraging trend of increased research attention to the subject in recent years, scientific evaluation of meditation is still in its early stages. While certain benefits
