HUGHLINGS JACKSON, in whose memory we are gathered this evening, had little to say about pain, but he was profoundly interested in what he termed impressions at the higher cortical level. He had this to say about the spinal cord:1
But such facts as that the cord has certain sized and certain shaped columns of white matter and certain shaped areas of grey matter are facts of morphology. So, too, are facts as to the course of fibres and arrangements of cells disclosed by microscopical examination. The latter is not minute anatomy, but minute morphology; and however minute it becomes it does not turn into physiology. It is only when the shapes of cells and course of fibres, etc. are shown to be subservient to the reception or conduction of particular impressions... that morphology ceases or rises into anatomy.
Here he has suggested just what we have been attempting
