The left hemisphere of the brain controls the right side of the body, and the right hemisphere controls the left side. In a split-brain patient, the two hemispheres are not connected, so each hemisphere can only control the opposite side of the body. Therefore, when Brendan sees the hammer with his left hemisphere, he will point to it with his right hand. Similarly, when he sees the glasses with his right hemisphere, he will point to them with his left hand.
