Nap it or leave it in the elderly: A nap after practice relaxes age-related limitations in procedural memory consolidation

Research output: Contribution to journal › Article › peer-review

Abstract

Using a training protocol that effectively induces procedural memory consolidation (PMC) in young adults, we show that older adults are good learners, robustly improving their motor performance during training. However, performance declined over the day, and overnight 'offline' consolidation phase performance gains were under-expressed. A post-training nap countered these deficits. PMC processes are preserved but under-engaged in the elderly; sleep can relax some of the age-related constraints on long-term plasticity.
