Spatial memory performance is associated with region-specific coordination of hippocampo-cortical sleep oscillations

The paper examines how coordination of sleep oscillations during nREM sleep relates to spatial memory performance in rats, finding region-specific coupling patterns between hippocampal and cortical areas.

Infraslow modulation of theta synchrony in the hippocampus circuit during REM sleep

The paper identifies infraslow modulation of theta synchrony in the hippocampal circuit during REM sleep, revealing temporally structured communication across brain regions.

Hippocampo-supramammillary coupling across sleep and wake

This study examines hippocampal communication with subcortical circuits across sleep and wake states in rats, revealing state-dependent bidirectional coordination and distinct temporal dynamics.

Hippocampal Synchrony Dynamically Gates Cortical Connectivity Across Brain States

This paper investigates how hippocampal ripple synchrony across dorsal and ventral regions gates cortical connectivity and memory consolidation during different brain states in rats.

Crossfrequency routing in a hippocampocortical circuit during probabilistic reversal learning

This study investigates how hippocampocortical circuits support probabilistic reversal learning by analyzing neural oscillations and spiking activity in rats.

Dentate gyrus somatostatin cells are required for contextual discrimination during episodic memory encoding

This study shows that somatostatin neurons in the dentate gyrus are essential for pattern separation during episodic memory encoding by modulating excitability and discrimination of similar environments in mice.

Cortical dynamics underlying social behavior in dominance hierarchy and spatial navigation

This study investigates how social context and dominance hierarchy influence decision-making during spatial navigation in mice, revealing the role of prefrontal cortex and hippocampus activity.
