Document Summary
*****m1 damage impairs voluntary behaviour; however, with practice the activity can be reacquired. The trained task is on left, controlled task is on right. Over the course of the three weeks of practice, for the particular trained task, there. M1 people practiced a speci c task & performed that task & a controlled task (cid:523)that. Take home message : for the brain, training is highly speci c. M1 sends the most extensive # of projections to the spinal cord , sma sends a little fewer and pma sends the least. Also, neurons within parietal node send some too. These all are the only cortical regions that send any connections directly to the spinal cord. Important b/c it gives us an understanding to what parts of the brain have direct control of the movement. Two hemispheres of the cerebral cortex are linked by the corpus callosum - a bundle of nerve fibres (white dura mater basically connecting two brains into one)
