Damage to the ascending forelimb afferents in the dorsal columns (DCs) of the cervical spinal cord in monkeys impairs forelimb use, particularly hand dexterity. Although considerable recovery has been reported, interpretation of the results is complicated by the reproducibility of the lesion and behavioral assessment. Here, we examined the effects of a unilateral DC lesion at the C4-C6 spinal cord level in four adult squirrel monkeys. Behavioral performance was assessed on a reach-to-grasp task… CONTINUE READING
