The vagus nerve drives cognitive function through the default mode network

This study shows that vagus nerve stimulation activates the default mode network, enhancing cognitive behaviors, while vagal-independent mechanisms affect the salience network.

Stressor-specific dynamic patterns of noradrenaline release in the paraventricular nucleus of the hypothalamus in freely moving mice

This study investigates stressor-specific patterns of noradrenaline release in the PVN of freely moving mice using a fluorescent sensor, revealing distinct temporal dynamics across different stressors.

Machine learning-based decoding of emotional valence from electrophysiological signals in the monkey brain

This study uses machine learning to decode emotional valence from electrophysiological signals in monkeys, finding that a Transformer model outperforms a CNN in classifying valence types.

Distinct roles of dentate gyrus and medial entorhinal cortex inputs for phase precession and temporal correlations in hippocampal CA3 place cells

Effects of novelty and temporal distance on post-experience reactivation of hippocampal place cells encoding multiple environments

This study examines how novelty and temporal distance affect post-experience reactivation of hippocampal place cells in rats, showing distinct roles for CA3 and CA1 in processing novelty and temporal aspects of memory.

Weak representation of awake/sleep states by local field potentials in aged mice

This study shows that aged mice show reduced representation of awake/sleep states in local field potential correlations, which can be partially restored with environmental enrichment.

Prefrontal-amygdalar oscillations related to social interaction behavior in mice

The paper examines oscillatory activity in the prefrontal cortex and amygdala of mice during social interactions, finding specific frequency changes linked to social behavior and deficits.

Prioritized experience replays on a hippocampal predictive map for learning

The paper shows that hippocampal replays prioritize salient experiences and support the reinforcement of new behavioral policies during learning.

Sharp wave-associated activity patterns of olfactory cortical neurons in the mouse piriform cortex

This study investigates neural activity patterns in the mouse piriform cortex during sharp wave events, finding non-random organization and coordinated activation of specific neuron pairs.
