This study shows cortical ripples occur during human NREM sleep and waking with similar characteristics to hippocampal ripples, associated with upstates, spindles, and unit co-firing, suggesting a role in memory consolidation.

This paper shows that high-frequency ripples synchronize cortical activity across distant brain regions during sleep, waking, and memory recall, supporting the binding-by-synchrony theory.

The paper shows that sleep spindles vary continuously across multiple dimensions rather than being strictly divided into slow and fast categories.

This study examines the interaction between cortical slow oscillations and hippocampal ripples during sleep using a computational model and human recordings, finding that ripples influence cortical spatiotemporal patterns and synchronize state transitions.

This study identifies and differentiates human hippocampal sharpwave-ripples (HC-SWR) from epileptiform activity during NREM sleep, showing similar characteristics to rodents but with lower frequency.

This study shows that human hippocampal sharpwave-ripples (HC-SWR) are correlated with various cortical sleep waves during NREM sleep, with specific spatial and temporal preferences.

The paper identifies distinct physiological patterns of hippocampal spindle-ripples in humans, showing they differ from sharpwave-ripples in timing, cortical coupling, and frequency.

The paper identifies replay of waking cortical activity patterns during slow-wave sleep in humans and links them to sleep features like spindles and sharp-wave ripples, supporting memory consolidation theories.
