Researchers reveal new findings on the complexity of age-related memory decline and neural dedifferentiation, challenging existing theories on cognitive aging. The study utilized functional MRI to compare brain activity patterns in young and older adults, revealing that age diminishes the brain's precision in processing visual information, with distinct mechanisms affecting category and item-level selectivity.
