Nyx: a flexible framework for sleep scoring across species, lifespan and modalities

Nyx is an unsupervised framework for sleep scoring that generalizes across species, lifespan, and modalities, achieving human-level agreement on diverse datasets.

Sleep spindles enhance latent working memory representations

This study shows that longer sleep spindle duration during NREM sleep improves post-sleep working memory performance and decoding of latent memory representations.

Feature and space-based interference with functionally active and passive items in working memory

The paper investigates whether active and passive items in working memory differ in susceptibility to interference, finding no significant difference in their vulnerability.

The phosphodiesterase-5 inhibitor vardenafil reverses sleep deprivation-induced amnesia in mice

This paper shows that vardenafil, a PDE5 inhibitor, can reverse sleep deprivation-induced amnesia in mice when combined with optogenetic engram stimulation, enhancing memory reactivation in the dentate gyrus.

Maintenance of colour memoranda in activity-quiescent working memory states: Evidence from impulse perturbation

This study uses impulse perturbation to investigate how non-spatial color memoranda are maintained in working memory, finding that both cued and uncued colors can be decoded from neural activity, with differences in alpha band oscillations.

Restoring persistent accessibility to memories after sleep deprivation-induced amnesia

This study shows that sleep deprivation does not cause memory loss but suboptimal storage, which can be retrieved using optogenetics or roflumilast.

Two faces of perceptual awareness during the attentional blink: Gradual and discrete

The paper investigates perceptual awareness during the attentional blink and finds it can be both gradual and discrete, depending on attentional focus.
