Evidence is given of the location in the spinal cord of man of the central sympathetic fibres supplying vasomotor and sudomotor neurons of the body caudal to the head and neck. The evidence is based on anterolateral cordotomies. The fibres lie within the medial part of the equatorial plane, extending from the base of the posterior horn and the lateral horn across the medial half of the white ma...
