Abstract

Until recently, many workers, following Brown-Séquard, held that impressions of pain and temperature pass upward through the gray matter, while those of touch and sense of position ascend through the dorsal columns. Petrén,1 from a collection of reports of a large number of cases, concluded that impressions of pain and temperature pass through the opposite lateral column, and of the muscle sense through the homolateral dorsal column, while two paths are open to touch, one through the uncrossed exogenous fibers of the dorsal column, and another in the opposite lateral column.

Head and Thompson2 confirmed these conclusions and showed that the ability to recognize the simultaneous contact of two compass points depends on impulses traveling through the homolateral dorsal column. Head and Holmes3 found that the appreciation of weight and recognition of size and shape are frequently lost on the paralyzed side, and concluded that the impulses
