ABSTRACT
The majority of neurological disorders cause disturbances in impulse traffic within the nervous system or between the nervous system and effector organs. Some disorders are degenerative, i.e. the tissue is destroyed, while others are functional, i.e. the function is disturbed without visibly altering or damaging anatomical structures. As a rule, damaged or degenerated neural tissue cannot be repaired. In the peripheral nervous system, however, a damaged axon can regenerate, but if cell bodies are destroyed, the neuron will die and no new neurons can completely replace the function. The central nervous system, on the other hand, has a certain amount of plasticity, where an adjoining healthy area can partially undertake the functions of a damaged area.
