Document Summary

Plasticity is the ability of the brain to change structurally and functionally as a result of input from the environment. Demonstrated by learning and remembering, changes in cortical maps, and microscopic changes in molecular structure and mitotic activity. Give some of the examples of plasticity in cortical maps that were mentioned in class. Somatosensory, motor, and visual cortex remapping: pascual leone braille learning. Give some of the examples of plasticity in synaptic structure that were mentioned in class (typists/salespeople) Dendritic trees become more complex as more fine/complex motor skills are acquired. Loss of function and electrical activity due to cerebral lesions in areas remote from the lesion but neuronally connected to it (contralesional damage). recovery of functions distally located to the area of insult after temporary neuronal disruption. What is the recovery path in hemiplegia? slow recovery is parallel to that of reach & grasp among infants.
