REM Sleep Iota Oscillations Across the Lifespan

This study examines iota oscillations in REM sleep across age groups, finding age-related changes in frequency, amplitude, and bandwidth, with high heritability for most properties.

Emotional memories are enhanced when reactivated in slow wave sleep, but impaired when reactivated in REM

The paper investigates how emotional memory consolidation during sleep stages affects memory retention, finding that reactivating memories during slow wave sleep enhances them, while reactivation during REM impairs them.

Influences of time of day on generalization

This study investigates how time of day affects generalization ability, finding better performance in the morning than the evening, with no benefit from sleep.

Phase-based coordination of hippocampal and neocortical oscillations during human sleep

The paper identifies three classes of phase-based communication between hippocampal and neocortical regions during sleep, highlighting the role of hippocampal slow oscillations in memory consolidation.

Sharp wave-ripples in human amygdala and their coordination with hippocampus during NREM sleep

This study identifies sharp wave-ripples in human amygdala during NREM sleep and shows their coordination with hippocampal activity, supporting a role in emotional memory consolidation.

Heterogeneous profiles of coupled sleep oscillations in human hippocampus

This study characterizes cross-frequency coupling in human hippocampal sleep oscillations during NREM and REM sleep using intracranial and scalp recordings.

Sleep selectively stabilizes contextual aspects of negative memories

The paper examines how sleep affects the retention of negative and neutral memories, finding that sleep selectively stabilizes negative contextual memories.

Large-Scale Structure and Individual Fingerprints of Locally Coupled Sleep Oscillations

The paper characterizes the spatial and temporal dynamics of slow oscillation-spindle coupling during sleep and finds individual variability in coupling phase that is stable across nights but not linked to memory change.

Variability and stability of large-scale cortical oscillation patterns

This study characterizes large-scale cortical oscillation patterns across individuals and time, finding both common templates and stable individual-specific networks.

Individual differences in frequency and topography of slow and fast sleep spindles

This study characterizes individual variability in slow and fast sleep spindle frequency and topography using EEG recordings and introduces a method to reliably separate spindle components across sleep stages.
