Overnight verbal memory retention correlates with the number of sleep spindles
TLDR
Evidence is provided that overnight verbal memory retention is highly correlated with the number of sleep spindles detected by an automatic algorithm over left frontocentral areas, and theories suggesting a link between sleep spindle activity and verbal memory consolidation are supported. Expand
Temporal coupling of parahippocampal ripples, sleep spindles and slow oscillations in humans.
TLDR
Ripples were consistently associated with interictal spikes suggesting that spike-ripple complexes represent an epileptic transformation of sharp wave-ripples complexes in the epileptic hippocampus, consistent with the notion of a hippocampo-to-neocortical information transfer during sleep that is linked to coordinate ripple and spindle activity. Expand
Fine‐tuned coupling between human parahippocampal ripples and sleep spindles
TLDR
The demonstration of spindle phase‐locked ripple activity in humans is consistent with the idea of a temporally fine‐tuned hippocampus‐to‐neocortex transfer of information taking place during SWS. Expand
Twenty-four hours retention of visuospatial memory correlates with the number of parietal sleep spindles
TLDR
It is shown that retention of visuospatial memories over a 24-h period correlates with the total number of sleep spindles detected over parietal regions during the intervening night-time sleep, which provides further evidence for the association between sleep spindle activity and declarative memory consolidation. Expand
Prediction of general mental ability based on neural oscillation measures of sleep
TLDR
Results suggest that individual differences in general mental ability are reflected in fast sleep spindle‐related oscillatory activity measured over the frontal cortex. Expand
Spike frequency is dependent on epilepsy duration and seizure frequency in temporal lobe epilepsy.
TLDR
Seizure frequency and epilepsy duration (years of patient's life with seizure activity) were independently associated with IED frequency, suggesting that IED are modulated by seizures. Expand
Correction of vitamin D deficiency improves seizure control in epilepsy: A pilot study
TLDR
It is found that seizure numbers significantly decreased upon vitamin D3 supplementation, and it is concluded that the normalization of serum vitamin 25(OH)D level has an anticonvulsant effect. Expand
Phase coupling between rhythmic slow activity and gamma characterizes mesiotemporal rapid-eye-movement sleep in humans
TLDR
A phase coupling closely resembles that seen between theta and gamma in rodents in rodents and is considered to be an additional reason for regarding delta rather than theta as the human analogue of RSA in animals. Expand
Increased mesiotemporal delta activity characterizes virtual navigation in humans
TLDR
frequency bins affected in a virtual navigation task in 24 epilepsy patients implanted with foramen ovale electrodes were similar to those characterizing REM sleep in previous studies providing further indication that it is delta rather than theta that should be regarded as a human analog of the animal RSA. Expand
Comparison of fractal and power spectral EEG features: Effects of topography and sleep stages
TLDR
It is found that cross-correlations between fractal and spectral measures as well as between H and ΔD exhibit specific topographic and sleep stage-related characteristics, suggesting that assessing multifractality might be an adequate approach for compact modeling of brain activities. Expand
