  1. Dear Dr Campbell, about the cross over of the fibers in the spinal cord : Imagine you are hit on the right side of the head, you will fall on your left side, your left arm may be crushed and useless, while your right arm could lift the boulder or tree trunk that pushed you down. That's because you find it difficult to imagine why it is so. We originaly came from a very dangerous environment. Thanks from Marseille France for your communications . They helped so many of us know where to look for trustworthy information in times of darkness.
