Energy levels in certain areas of the brain surge during early stages of sleep, indicating that the increase in cellular activity may actually replenish the body’s most important organ, according to a study that was published in the Journal of Neuroscience.

When looking at the brain activity of rats, researchers observed a spike in energy in four areas that are typically active during wakefulness.

“This research provides intriguing evidence that a sleep-dependent energy surge is needed to facilitate the restorative biosynthetic processes,” said sleep expert Robert Greene, M.D., Ph.D.

Even in the subconscious, the brain has the ability to heal itself and become a stronger organ.

For years, author and philosopher Ilchi lee has touted the benefits of healthy living and Brain Education techniques for overall well-being. His methods include meditation in which an individual focuses on the brain to eliminate negativity and encourage positive thinking and actions.

This research supports his ideas that the brain has great potential and energy to support an enlightened being, even at times when they are not consciously trying.
