Document Summary
By crushing), individual axons regenerate to their correct targets. Release neurotrophins for re-stimulating nerves: disabling neuro regrowth to occur, oligodendrocytes do . Release chemicals that actively inhibit regeneration of nerves. Nogo convenient name for protein/chemical (basically means. [cortical reorganization: cortical reorganization can be good , strengthens existing neural connections, expansion of surviving neural connections, cortical reorganization may also cause dysfunction that was not there before (ex. phantom limb syndrome). Rarely any improvement in clinical condition, often, pain became worse or more spread-out to new phantom limbs: somatosensory plasticity, some patients with phantom limbs can actually feel the limb by touching other parts of the body. Example: phantom hand on the patient"s cheek, pricking arm, but feel it on the face, vs ramachandran. Axons from phantom arm may connect to neighboring areas (ex. Face): these areas are closely situated in the somatosensory homunculus, mirror box therapy.
