Chondroitinase ABC promotes selective reactivation of somatosensory cortex in squirrel monkeys after a cervical dorsal column lesion.
After large but incomplete lesions of ascending dorsal column afferents in the cervical spinal cord, the hand representation in the contralateral primary somatosensory cortex (area 3b) of monkeys is largely or completely unresponsive to touch on the hand. However, after weeks of spontaneous recovery, considerable reactivation of the hand territory in area 3b can occur. Because the reactivation ...
متن کاملThermostabilized chondroitinase ABC Promotes Neuroprotection after Contusion Spinal Cord Injury
Background: Chondroitinase ABC (cABC), due to its loosening impact on the extracellular matrix scaffold, has been used to enhance regeneration of injured axonal tracts after spinal cord injury (SCI). However, cABC thermal instability at physiological temperature has limited its clinical application. The disaccharide trehalose has been shown to increase the stability of cABC in body temperature....

متن کاملReorganization of somatosensory cortical areas 3b and 1 after unilateral section of dorsal columns of the spinal cord in squirrel monkeys.
An incomplete lesion of the ascending afferents from the hand in the dorsal columns of the spinal cord in monkeys is followed after weeks of recovery by a reactivation of much of the territory of the hand representations in primary somatosensory cortex (area 3b). However, the relationship between the extent of the dorsal column lesion and the amount of cortical reactivation has not been clear. ...
متن کاملSomatosensory Cortex in Owl Monkeys
1. Several features of the two complete and separate representations of the contralateral body surface in cortical areas 3b and 1 of somatosensory cortex in owl monkeys were quantitatively studied. 2. Area1 magnification factors for different body regions in the two representations were obtained. The glabrous hand and foot regions were found to occupy nearly 100 times more cortical tissue per u...
