Reorganization of Memory
When there is damage to just one side of the MTL, there is opportunity for normal functioning or near-normal function for memories. Neuroplasticity describes the ability of the cortex to remap when necessary. Remapping can occur in cases like the one above, and, with time, the patient can recover and become more skilled at remembering. A case report describing a patient who had two lobectomies - in the first, doctors removed part of her right MTL first because of seizures originating from the region, and later her left because she developed a tumor — demonstrates this. This case is unique because it is the only one in which both sides of the MTL were removed at different times. The authors observed that the patient was able to recover some ability to learn when she had only one MTL, but observed the deterioration of function when both sides of the MTL were afflicted. The reorganization of brain function for epileptic patients has not been investigated much, but imaging results show that it is likely.

Famous quotes containing the word memory:
“‘Tis of the essence of life here,
Though we choose greatly, still to lack
The lasting memory at all clear,
That life has for us on the wrack
Nothing but what we somehow chose;
Thus are we wholly stripped of pride
In the pain that has but one close,
Bearing it crushed and mystified.”
—Robert Frost (1874–1963)
