Although the neurological basis of phantom limb sensation is not completely understood yet, cortical recombination is thought to play an important role. Follow Michael Marginic Leader, Norman Dojge Neuroplasticity has a positive or negative effect divided into adaptive behaviors. For example, if an organism can return to a normal functional level after a stroke, this fitness can be thought of as an example of "positive plasticity". Excessive levels are thought to be "negative" as an example of plasticity, neurons leading to tonic convulsions and paralysis, or excessive release of neurotransmitters, in response to nerve injury possibly leading to cell death.
