Olfactory and Sensory Function Studies

The paper identifies two distinct subpopulations of VP cholinergic neurons that encode valence of olfactory stimuli and differentially regulate approach and avoidance behaviors.

This study shows mice can discriminate odor plume intermittency and the olfactory bulb encodes this property, with sniffing behavior influencing both performance and neural representation.

This study shows that metabolic state affects odor processing in the human olfactory bulb, with higher gamma power observed during hunger compared to satiety.

This study investigates how mouse olfactory bulb spiking activity encodes temporal features of natural odor plumes, finding that population-level activity captures plume onset, offset, and presence/absence, while individual cells encode only limited features.

This study generates single-cell transcriptomic atlases of the mouse vomeronasal organ, revealing new cell types, lineage relationships, and molecular mechanisms of receptor specification.

This study shows dopamine in the ventral striatum initiates sniffing by modulating respiratory rate and neuronal activity.

This study investigates how inflammation in the olfactory epithelium affects the olfactory bulb in schizophrenia and related disorders, finding correlations between immune-related gene expression and OB volume reduction.

This study shows that lifelong olfactory enrichment in mice improves cognitive performance and brain connectivity, linked to noradrenergic plasticity and network remodeling in aging.

This study identifies Foxj1's role in regulating olfactory cilia formation and OSN differentiation in zebrafish and mice.

The paper performs single-cell transcriptomics on mouse vomeronasal sensory epithelium to identify cell types and functional differences, finding distinct ER environments in neuronal subtypes.

This study uses fMRI to investigate whether nostril-specific odor stimulation produces asymmetrical activation in olfactory cortical structures in humans.

This study examines how context and experience influence neural activity in the accessory olfactory bulb in response to social cues using fiberphotometry.

The paper uses engineered odorant receptors to uncover structural principles of odor discrimination by solving cryoEM structures of consensus ORs and comparing their ligand recognition properties.

This study shows that short-term consumption of ultra-processed semi-synthetic diets impairs olfactory function and brain metabolism in mice.

The paper shows that odor information from each nostril is encoded separately in the piriform cortex, with ipsilateral odors processed faster than contralateral ones.

The paper replicates and extends findings showing that lifelong olfactory deprivation leads to orbitofrontal cortex morphological changes, but not in piriform cortex.

This study identifies the timing, frequency bands, and direction of odor valence communication between the olfactory bulb and piriform cortex using human neural activity and valence ratings.

This study shows that olfactory function can be preserved in mice with severe olfactory bulb degeneration due to altered circuitry compensating for lost structures.
