VII. Principles of Psychosomatic Physiology

[^3]: In September 1954, forty-seven years after the above words were written, Dr. J. A. V. Bates of the neurological Research Unit (National Hospital) read his paper, Can Voluntary Movement be Localized in the Cerebral Cortex? to a meeting of the British Association at Oxford. He began by demonstrating, on a number of technical grounds, that the inferences drawn from certain well-known facts of observation are not valid inferences, since those facts do not prove that the so-called motor nerve implements movement in the manner that the theory of two kinds of nerve fibre assumes. We should, he suggested. “cease to regard the cerebro-spinal tract as an efferent tract from an area where movements are represented”; and he drew attention to the fact that a similar interpretation of the then observed facts had been brought forward by Francois Franck as long ago as 1886 but had been rejected in flavour of Ferrier’s hypothesis of efferent and afferent nerve fibres.
