Dynamic reorganization of digit representations in somatosensory cortex of nonhuman primates after spinal cord injury.
Somatosensory cortices of adult primates reactivate over time after sensory loss. The time course and the neural mechanisms underlying the cortical reactivation are not well understood. Here we report that longitudinal high-resolution functional magnetic resonance imaging (fMRI) studies on anesthetized squirrel monkeys revealed dynamic reorganizations of digit activations in area 3b, within 2 m...
متن کاملAssessment of median nerve somatosensory evoked potentials in cerebral ischemia.
Seventy patients with cerebral ischemia (21 with transient ischemic attack and 49 with stroke) were studied with short-latency median nerve somatosensory evoked potentials to characterize the evoked potentials in all ischemic patients and to investigate their efficacy for prognosis in stroke. Within 72 hours of symptom onset, all 70 patients received a scaled neurologic function score, with a m...
متن کاملPositive prognostication from median-nerve somatosensory evoked cortical potentials.
BACKGROUND The bilateral absence of the cortical N20 median-nerve somatosensory evoked potential (SSEP) is a strong predictor of poor outcome from coma. However, when N20s are present, accurate prognostication is challenging. Here, we investigated the potential for later SSEP components to help disambiguate outcome in these cases. METHODS In a retrospective review of data from two intensive c...
متن کاملSensory recovery after forearm median and ulnar nerve grafting.
BACKGROUND Median and ulnar nerve injuries are common, whether isolated or combined injury of both nerve. A nerve graft, if performed in a tensionless manner, has been shown to generally have better results than an end-to-end approximation performed under tension. OBJECTIVE The aim of this study is to analyze the long-term results of sensory recovery after secondary reconstruction median and ...
متن کاملHereditary aspects of median-ulnar nerve communications.
Median-ulnar nerve communications, resulting in anomalous innervation of intrinsic hand muscles, was found to occur in 28% of the general population and 62% of family members of five propositi with this variant. This variant appears to be dominantly inherited.
