Re-establishing the disrupted sensorimotor loop in deafferented and deefferented people: The case of spinal cord injuries

摘要: Acting efficiently in the world depends on activity of motor and somatosensory systems, integration which is necessary for proper functioning sensorimotor loop (SL). Profound alterations SL follow spinal cord injury (SCI), a condition that brings about disconnection body from brain. Such creates substantial deprivation somatosensorial inputs outputs. Consequent somatic deficits paralysis affect below lesion level. A complete restoration normal functions cannot be expected until basic neuroscience has found way to re-establish interrupted neural connectivity. Meanwhile, studies should focus development technical solutions dealing with disruption loop. This review discusses structural functional adaptive reorganization brain after SCI, maladaptive mechanisms impact processing related information, alter imagery strategies EEG signals. Studies show how residual (e.g. face tactile sensitivity) may help people restore image are also reviewed. Finally, data signals used improve computer interface systems discussed relation issue such SCI re-enter interact objects other individuals.
