Hughlings Jackson called attention to the remarkable fact that the nervous system is double, and he admonished future neurologists to consider the significance of this construction. Nevertheless, the fact that in each human there are two complete nervous systems – a right and a left – has been largely neglected by the neurophysiologists, and has been explored primarily as a consequence of unilateral cortical trauma or surgery. From these studies it is clear that the human cerebral cortex is functionally [...]
