Similarly armchair: An alternative to reducing the bridge might be trying to actively increase it - the brain reconfigures (right?) so perhaps we can with careful drug use open up the dark area and allow the regular brain to use that sector again. The difference between cleaning a room in your house and nailing the door shut.<p>Maybe that is in part what is happening anyway? Or is there evidence to show that the section of the brain becomes under-utilised. (no I didn&#x27;t RTFA; will get right on it!)
