Meditation has attracted substantial interest from scientists, who are now able to use new technologies to see exactly what goes on inside the brains of individuals who practice meditation. Research has shown that regular meditation actually alters the way the brain is wired, and that these changes could be at the core of claims that meditation can improve health and wellbeing. Recent research indicates that meditating, even for just ten minutes, can have dramatic effects. Several studies have demonstrated that the brains of people who meditate, even for a short time, generate a higher frequency of alpha waves (electromagnetic waves produced by a relaxed brain) and experience less anxiety and depression. To discover which part of the brain is most influenced by meditation, researchers at Harvard Medical School used high-resolution magnetic resonance imaging (MRI) technology on participants to monitor their brain activity as they meditated.
