This study examines the infraslow fluctuation of sigma power during sleep across development, finding it persists with increasing frequency and strength from childhood to young adulthood.

This study shows that a mutation in synaptobrevin 2 in mice leads to abnormal cortical activity patterns across sleep and wake states, resembling deep anaesthesia.

This study introduces a new metric, oscillatory Quality (o-Quality), to quantify sleep spindle oscillatory strength in mice and links it to functional roles in sleep.

The paper proposes frequency-dependent safety thresholds for temporal interference stimulation (TIS) by comparing it to established brain stimulation methods using biophysical simulations.

This paper introduces a framework for linear causal filtering using multivariate autoregressive modeling to estimate directional causal information flow from non-directional association measures.

The paper identifies biases in brain connectivity inference from electrophysiological signals due to noise and introduces a method to correct for these biases.

The paper shows that 2:1 harmonic alpha:theta cross-frequency relationships increase from meditation to arithmetic tasks in experienced meditators.

This study develops mathematical models of sleep homeostasis in mice, showing Process S integrates local cortical neuronal activity over time to regulate sleep quantity.
