brain it supplies
but do know, right side stroke affects the left side of the body BUT only affects right eye
left side stroke affects the right side of the body BUT only affects the left eye.

5) affect: difficulty controlling emotions
6) elimination ; hard time pooping and peeing but this is temporary
