Daytime Sleep Enhances Consolidation of the Spatial but Not Motoric Representation of Motor Sequence Memory
Geneviève Albouy,Stuart Fogel,Hugo Pottiez,Vo An Nguyen,Laura B. Ray,Ovidiu Lungu,Julie Carrier,Edwin M. Robertson,Julien Doyon +8 more
TL;DR: It is shown that both allocentric (spatial) and egocentric (motor) representations of the sequence can be isolated after initial training, and that sleep-dependent gains in performance observed for the allocentric representation are correlated with spindle density during non-rapid eye movement (NREM) sleep of the post-training nap.
Journal ArticleDOI
Changes in the density of stage 2 sleep spindles following motor learning in young and older adults.
TL;DR: The results of the present study are largely consistent with previous studies on sleep and memory in young adults and suggest that more detailed examination of this relationship in older adults is warranted.
Journal ArticleDOI
Validating an automated sleep spindle detection algorithm using an individualized approach.
TL;DR: Given that interindividual differences are accounted for, it is felt that automatic spindle detection provides an accurate and efficient alternative approach for detecting sleep spindles.
Journal ArticleDOI
Expert and crowd-sourced validation of an individualized sleep spindle detection method employing complex demodulation and individualized normalization.

TL;DR: This method of automated spindle detection resolves or avoids many of the limitations that complicate automatedSpindle detection, and performs well compared to a group of non-experts, and importantly, has good external validity with respect to the extant literature in terms of the characteristics of automatically detected spindles.
Journal ArticleDOI
Waking quantitative electroencephalogram and auditory event-related potentials following experimentally induced sleep fragmentation.
TL;DR: Electroencephalographic and event-related potentials data illustrate impairment in information-processing capabilities associated with reduced arousal elicited by experimental sleep fragmentation, which leads to sustained impairment in alertness and attention.
