Leison is what is been seen in the brain as white Spot it is as a result of activities carried out in the brain. MR monitors how blood flows into a part of the brain will then transfer the lesion into the brain.
Myaline sheets surround the nerves cells forming a layer round the axons.
Break down of Myaline sheathe leads random shot of neurons this then result in white leison. The leison disappers after the myelin sheat have been healed or repaired by the actions of the neuron present.
Neurons then carries signals or impulse that the myelin sheat have been fixed.
