College may endow memory to old brains
By Bruce Bower
Educated brains stave off declines in memory that typically occur as people age, a new brain-imaging investigation suggests.
College-educated older adults do better on memory tests than their less-educated peers do and also display pronounced frontal-brain activity during memory testing, say Mellanie V. Springer of the University of Toronto and her colleagues. College-educated young adults scored higher than either their less-educated peers or comparably educated elders do and, during memory tests, exhibited intense responses in their temporal lobes, which are on the brain’s flanks.
