Abstract
Maximizing recovery of function after brain injury is the goal for many neuroscientists and rehabilitation medicine professional alike. To further elucidate the neural mechanisms underlying compensatory changes in brain injury and to determine the possibility of enhancing these changes, three experiments are described. Experiment 1 looks at the effects of structured (skilled reaching) versus functional (enriched environment) training with and without FGF-2, a pharmacological intervention, as treatment paradigms for rehabilitation-induced recovery of function in cortical lesion adult rats. Experiment 2 examines the treatment effects of tactile stimulation to enhance motor abilities in postnatal day 4 rat pups sustaining cortical damage. Finally, experiment 3 explores changes in the cortical motor representation after cortical damage. Results indicate a marked improvement on behavioral testing combing FGF-2 and functional training. Tactile stimulation significantly enhances recovery of motor functions. Post-lesion cortical mapping reveals changes in the motor representation utilizing the adjacent posterior parietal cortex.
