If someone reaches a higher brain wave (Theta) through meditation, our brain can rejuvenate by itself and it also has a substantial effect on our brain. After 8 consecutive weeks of meditation, the small brain or reptilian brain (Amedila), where we control our emotion, gets smaller. Consequently, meditators reduce stress and anxieties and are able to control their emotions better. On the other hand the frontal part of the brain or prefrontal Cortex, which controls the whole function of our brain, becomes larger. As a result, meditators increase their brain function and develop more neuro paths. Meditators can work longer hours compared to non-meditators.
