Coupled sleep rhythms for memory consolidation

BP Staresina - Trends in Cognitive Sciences, 2024 - cell.com
How do passing moments turn into lasting memories? Sheltered from external tasks and
distractions, sleep constitutes an optimal state for the brain to reprocess and consolidate …

Coupling of sharp wave events between zebrafish hippocampal and amygdala homologs

I Blanco, A Caccavano, JY Wu, S Vicini… - Journal of …, 2024 - Soc Neuroscience
The mammalian hippocampus exhibits spontaneous sharp wave events (1–30 Hz) with an
often-present superimposed fast ripple oscillation (120–220 Hz) to form a sharp wave ripple …

Awake ripples enhance emotional memory encoding in the human brain

H Zhang, I Skelin, S Ma, M Paff… - Nature …, 2024 - nature.com
Enhanced memory for emotional experiences is hypothesized to depend on amygdala-
hippocampal interactions during memory consolidation. Here we show using intracranial …

Impact of single‐trial avoidance learning on subsequent sleep

Q Zhang, F Chen - European Journal of Neuroscience, 2024 - Wiley Online Library
Both non‐rapid eye movement (NonREM) sleep and rapid eye movement (REM) sleep, as
well as sleep spindle and ripple oscillations, are important for memory formation. Through …

Depth-based statistical analysis in the spike train space

X Zhou, W Wu - Journal of Applied Statistics, 2024 - Taylor & Francis
Metric-based summary statistics such as mean and covariance have been introduced in
neural spike train space. They can properly describe template and variability in spike train …

Self-avoidance dominates the selection of hippocampal replay

CS Mallory, J Widloski, DJ Foster - bioRxiv, 2024 - biorxiv.org
Spontaneous neural activity sequences are generated by the brain in the absence of
external input, yet how they are produced remains unknown. During immobility …

Rescuing impaired hippocampal-cortical interactions and spatial reorientation learning and memory during sleep in a mouse model of Alzheimer's disease using …

SD Cushing, SC Moseley, AC Stimmell… - bioRxiv, 2024 - biorxiv.org
In preclinical Alzheimer's disease (AD), spatial learning and memory is impaired. We
reported similar impairments in 3xTg-AD mice on a virtual maze (VM) spatial-reorientation …

A Hippocampal-parietal Network for Reference Frame Coordination

Y Zheng, X Zhou, SC Moseley, SM Ragsdale, LJ Alday… - bioRxiv, 2024 - biorxiv.org
Navigating space and forming memories based on spatial experience are crucial for
survival, including storing memories in an allocentric (map-like) framework and conversion …

[PDF][PDF] Hippocampal Ripples are Correlated with Subthreshold Up/Down Activity in Mouse Posterior Parietal Cortical Neurons

H Mizuno, Y Ikegaya - New Adv Brain & Critical Care, 2024 - opastpublishers.com
Memories acquired during wakefulness are consolidated during sleep. During non-rapid
eye movement (NREM) sleep, ripples occur in the hippocampus, while slow oscillations …
