Master AND commander

Master commanderAn fMRI scan of the upper echelons of the human brain, reveals that there are apparently two commanders at the helm, according to US neuroscientists; it is as if Russell Crowe were joined by his twin brother to captain the ship. The work may suggest new insights into behavioural problems that occur following brain injury.

Neuroscientist Steven Petersen and his team at Washington University School of Medicine in St. Louis also found that these two captains at a single helm do not consult each other in the control of voluntary, goal-oriented behaviour. Such behaviour encompasses a vast range of activities from reading and surfing the net to singing a song or even sailing a ship. In contrast, involuntary behaviour, such as pulse rate, breathing, and digestion are not controlled in this way.
