Sleep spindles and their significance for declarative memory consolidation.
STUDY OBJECTIVES Functional significance of stage 2 sleep spindle activity for declarative memory consolidation. DESIGN Randomized, within-subject, multicenter. SETTING Weekly sleep laboratory visits, actigraphy, and sleep diary (4 weeks). PARTICIPANTS Twenty-four healthy subjects (12 men) aged between 20 and 30 years. INTERVENTIONS Declarative memory task or nonlearning control task be...
متن کاملAge-related changes in sleep spindles characteristics during daytime recovery following a 25-hour sleep deprivation
OBJECTIVES The mechanisms underlying sleep spindles (~11-15 Hz; >0.5 s) help to protect sleep. With age, it becomes increasingly difficult to maintain sleep at a challenging time (e.g., daytime), even after sleep loss. This study compared spindle characteristics during daytime recovery and nocturnal sleep in young and middle-aged adults. In addition, we explored whether spindles characteristics...
متن کاملSleep Spindles
The development of EEC sleep-spindles in prematurely-born and full-term infants was studied to test an hypothesized impact of experience (longer extrauterine existence) upon innate maturational factors (EEG development). The age of otiset of sleep spindles and achievement of mature spindle quality occurs approximately 4 weeks earlier in prematurely-born infants than in full-term infants. Sleep ...
متن کاملCoordinated Interactions between Hippocampal Ripples and Cortical Spindles during Slow-Wave Sleep
Sleep is characterized by a structured combination of neuronal oscillations. In the hippocampus, slow-wave sleep (SWS) is marked by high-frequency network oscillations (approximately 200 Hz "ripples"), whereas neocortical SWS activity is organized into low-frequency delta (1-4 Hz) and spindle (7-14 Hz) oscillations. While these types of hippocampal and cortical oscillations have been studied ex...
متن کاملDivergent Cortical Generators of MEG and EEG during Human Sleep Spindles Suggested by Distributed Source Modeling
BACKGROUND Sleep spindles are approximately 1-second bursts of 10-15 Hz activity, occurring during normal stage 2 sleep. In animals, sleep spindles can be synchronous across multiple cortical and thalamic locations, suggesting a distributed stable phase-locked generating system. The high synchrony of spindles across scalp EEG sites suggests that this may also be true in humans. However, prior M...
