REM sleep prefrontal high-frequency oscillation chains mediate distinct cortical-hippocampal reactivation patterns compared to NREM sleep

This study identifies distinct cortical-hippocampal reactivation patterns during REM and NREM sleep, mediated by prefrontal high-frequency oscillation chains in rodents.

Hippocampal-prefrontal communication subspaces align with behavioral and network patterns in a spatial memory task

The paper investigates how rhythmic network states influence communication subspaces between hippocampal and prefrontal cortex regions during a spatial memory task in rats, finding that shared subspaces rather than local activity correlate with behavior.

Cortical ripples mediate top-down suppression of hippocampal reactivation during sleep memory consolidation

This study shows that prefrontal cortex ripples suppress hippocampal reactivation during sleep, inversely related to reactivation strength during coordinated ripples.

Intrinsic dynamics of randomly clustered networks generate place fields and preplay of novel environments

This paper shows that random clustered neural networks can generate place fields and preplay of novel environments without pre-configured spatial maps.

Hippocampal theta sequences in REM sleep during spatial learning

This study investigates REM theta sequences in rats during spatial learning, finding they parallel waking theta sequences and support memory consolidation.

Multiple time-scales of decision making in the hippocampus and prefrontal cortex

This study investigates how hippocampal and prefrontal cortex sequences interact during memory-guided decision-making, revealing cooperative interactions at multiple timescales.

Awake hippocampal-prefrontal replay mediates spatial learning and decision making

The paper tracks hippocampal-prefrontal replay during spatial learning and shows it mediates internal cognitive search and decision-making through opposing learning gradients.

Coherent coding of spatial position mediated by theta oscillations in hippocampus and prefrontal cortex

This study shows that theta oscillations coordinate spatial position coding between hippocampus and prefrontal cortex during memory tasks in rats.
