title: Effects of dorsal column transection in the upper cervical segments on visually guided forelimb movements.
abstract: Complete transection of the dorsal column in C2 in cat gave severe defects in forelimb target-reaching and food-taking tested with retrieval of food from a cylinder. Among the symptoms were marked dysmetria in all directions and dyscoordination of movements in different joints, with only slow recovery over weeks and months. It is postulated that normal visual guidance of forelimb movements to a stationary target depends on somatosensory information to the brain via the dorsal column.
