Caption: Brain-hand control from MEG scan. Two computer images of the human brain (side view), depicting brain to hand nerve control. At left, milliseconds before a patient starts moving their right index finger, nerve cells in the motor area of the brain (yellow) send movement commands to the muscles involved. At right, 40 milliseconds later, the hand sensory area processes information from muscles and joints that the finger is moving. This rapid "real" time data of brain activity was obtained from magnetoencephalography (MEG). MEG is a technique that measures magnetic fields genera- ted from nerve activity in the brain. Photographed at New York University Medical Centre, USA.
