Training-induced recovery of manual dexterity after a lesion in the motor cortex.
Cerebral injury, such as stroke, cause functional deficits; however some functions can recover with postlesion rehabilitative training. Several recent studies using rodents and monkeys have reported the effects of postlesion training on functional recovery after brain injury. We present herein an overview of recent animal experimental studies on the effects of postlesion motor training on brain...
متن کاملEffects of motor training on the recovery of manual dexterity after primary motor cortex lesion in macaque monkeys.
To investigate the effects of postlesion training on motor recovery, we compared the motor recovery of macaque monkeys that had received intensive motor training with those that received no training after a lesion of the primary motor cortex (M1). An ibotenic acid lesion in the M1 digit area resulted in impairment of hand function, with complete loss of digit movement. In the monkeys that had u...
متن کاملTemporal plasticity involved in recovery from manual dexterity deficit after motor cortex lesion in macaque monkeys.
The question of how intensive motor training restores motor function after brain damage or stroke remains unresolved. Here we show that the ipsilesional ventral premotor cortex (PMv) and perilesional primary motor cortex (M1) of rhesus macaque monkeys are involved in the recovery of manual dexterity after a lesion of M1. A focal lesion of the hand digit area in M1 was made by means of ibotenic ...
متن کاملComparison of Functional Recovery of Manual Dexterity after Unilateral Spinal Cord Lesion or Motor Cortex Lesion in Adult Macaque Monkeys
In relation to mechanisms involved in functional recovery of manual dexterity from cervical cord injury or from motor cortical injury, our goal was to determine whether the movements that characterize post-lesion functional recovery are comparable to original movement patterns or do monkeys adopt distinct strategies to compensate the deficits depending on the type of lesion? To this aim, data d...
متن کاملMotor skills training enhances lesion-induced structural plasticity in the motor cortex of adult rats.
To assess behavioral experience effects on synaptic plasticity after brain damage, the present study examined the effects of complex motor skills training (the acrobatic task) on synaptic changes in layer V of the motor cortex opposite unilateral damage to the forelimb sensorimotor cortex (FLsmc). Adult male rats were given lesions or sham operations followed by 28 d of training on the acrobati...
