A reorganization of cortical representations is postulated as the basis for functional recovery following many types of nervous system injury. Neuronal mechanisms underlying this form of cortical plasticity are poorly understood. The present study investigated the hypothesis that the basal forebrain cholinergic system plays an essential role in enabling the cortical reorganization required for ...

traumatic brain injury (tbi) is described by a disruption in the normal function of the brain due to an injury following a trauma, which can potentially cause severe physical, cognitive, and emotional impairment. the use of human stem cells and self-assembling peptide scaffolds suggest huge potential for application in the treatment of tbi. in the present study, we surveyed the beneficial effec...

prior animal models have shown that rats sustaining 3-second immediate spinal cord compression had significantly better functional recovery and smaller lesion volumes than rats subjected to compression times of 1 hour, 6 hours, 3 weeks, and 10 weeks after spinal cord injury. we compare locomotor rating scales and spinal cord histopathology after 3 seconds and 10 minute compression times. . ten ...
