Meditation requires concentrating and focusing attention to the point that focus can be brought back into the spotlight when attention drifts. This practice over time is useful not just while meditating but otherwise as well. A study
by Eileen Luders, an assistant professor at the UCLA Laboratory of Neuro Imaging has shown that physical changes such as cortical folding that occurs with regular meditation, helps the brain process information better. This leads to better functioning of memory, attention, thought and consciousness.
