Abstract:
Studies suggest that the consolidation of newly acquired memories and underlying long‐term synaptic plasticity might represent a major function of sleep. In a combined repeated‐measures and parallel‐group sleep laboratory study (active waking versus sleep, passive waking versus sleep), we provide evidence that brief periods of daytime sleep (42.1 ± 8.9 min of non‐rapid eye movement sleep) in healthy adolescents (16 years old, all female), compared with equal periods of waking, promote the consolidation of declarative memory (word‐pairs) in participants with high power in the electroencephalographic sleep spindle (sigma) frequency range. This observation supports the notion that sleep‐specific brain activity when reaching a critical dose, beyond a mere reduction of interference, promotes synaptic plasticity in a hippocampal‐neocortical network that underlies the consolidation of declarative memory.
