--brain hemisphere/quadrant principals--

the concept--

  i suggest, that the right and left sides of the brain, are not truly separated, but are in fact, like two gears meshing together( similar to a vehicles differential)...for this reason, i feel that a person playing a piano, or doing geometry, is both using part of the logic( right), and part of the creative side( left), of their brain--

  furthermore, i feel that without one hemisphere of the brain working, more than just the loss of one side of the body would be produced...as reading sheet-music, and moving the hands fluently( while playing the piano), indicate to me, that both sides of the brain are in use( the left, and the right)--

conclusion--

  for this reason, i feel that the left, and right sides of the brain, have "quadrants", in use on the opposite side of the brain, and are in fact, like a root structure, going from the side being used, to the other side...through the "hippocampus"--
