The paper identifies a brainstem circuit that transmits both sensory and motor information from aversive experiences to the amygdala, enhancing defensive behaviors and emotional memory formation.

The paper shows that dmPFC neurons encode internal models of emotional associations, linking sensory stimuli with aversive events directly or indirectly.

The paper introduces a technique called PINCER to study the functional input-output organization of neurons in neural circuits, demonstrating its application in the amygdala to reveal aversive memory-related cell types.

This study shows that distinct subregions of the medial prefrontal cortex bidirectionally regulate emotional memory extinction through their influence on the locus coeruleus-noradrenaline system.

This study shows light exercise activates the dorsal hippocampus through noradrenergic and dopaminergic pathways in rats, enhancing memory function.

This study analyzes LC neuron firing patterns across species and biological factors, revealing diverse activity patterns and subregions enriched for specific factors and disease models.

The paper shows emotional association enhances perceptual memory through BLA-frontal projections during NREM sleep by increasing coordinated reactivation and disrupting memory retention when BLA inputs are silenced.

The paper maps afferent inputs to two functionally distinct noradrenaline cell types in the locus coeruleus and identifies sex-specific differences in their connectivity.

This study identifies the claustrum as a key subcortical hub coordinating neocortical slow-wave activity through synchronization of inhibitory interneurons during sleep and rest.

The paper identifies a sub-population of place cells that remap during learning and show unique firing property changes, supporting separate encoding of novel and familiar spatial information.
