Older people’s short-term memory is generally slower and less accurate compared to younger people. But a new University of California, Berkeley, study suggests that brains that continue to perform well in old age do so by rallying more of the brain to complete mental tasks.
The researchers suggest that the age-associated changes observed in network organization within the brain while performing short-term memory tasks might help compensate somewhat for other aspects of brain aging.
“We think this pattern of increased connectivity between frontal regions and other modules in the brain reflects a more integrated network architecture that is key for successful performance of executive control tasks in aging,” said UC Berkeley graduate student Courtney Gallen.
