Document Summary
Humans can modify their brain structures and functions. Based on external or internal stimulation, even in older adulthood fmri studies with before and after imaging for cognitive training show. Changes that occur in brain structure following various training programs. Sometimes there is more efficient use of specific brain regions. Sometimes there is compensation through alternative parts of the brain being used for activities. Brain plasticity new views of the aging brain. Brain plasticity research related to cognitive training. Beneficial process, helps to counteract adverse effects of neural and functional decline. Involves supplementary neural circuitry that helps support the aging brain when performing cognitive tasks. Positive form of plasticity in brains of older adults. As become better at specific tasks, scaffolding (neural circuitry) shifts to areas that need more help. Unless, or until, brain deterioration becomes so widespread that an older adult loses this scaffolding ability. Generics, lifestyle factors, and environment play a role in.
