Locus coeruleus is the part of the brain which is responsible for attention, memory and cognition control(meaning the process of acquiring knowledge and understanding through thought) and emotion. Now that you know what it does and why we need it in our day to day life here’s something which you might find interesting.
Richard Wiseman in his book “59 Seconds” suggested to lie down on the floor to get the creative juices flowing. In the TV series “House M.D.”, Dr. House is seen lying down on the floor while thinking and that too in his office. Since he is a sociopath and a moron who doesn’t care what others think of him, lying flat in his office seemed to me his way of thinking and it never occurred to me that he might be doing that for a reason. Lying flat on the floor increases the blood flow in Locus coeruleus and we become more creative.
