This paper introduces a synthetic MRI-derived contrast (FD) to detect microstructural changes in olfactory-limbic circuits associated with mild cognitive impairment.

This study investigates how the brain integrates olfactory and trigeminal signals using fMRI and psychophysics, finding multisensory integration in specific brain regions.

This paper identifies a neurocognitive state linked to increased perceptual errors in radiologists, detectable via brain imaging and associated with a threefold risk increase.

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

This study examines olfactory network functional connectivity in Parkinson's disease subtypes, finding impaired connectivity in akinetic-rigid patients linked to worse clinical outcomes.

This study identifies FDG hyper-metabolism in cerebellar and olfactory regions in Alzheimer's disease, suggesting disrupted inhibitory networks.

This study shows that olfactory co-stimulation improves the localization of weak intranasal somatosensory stimuli when the stimuli are delivered to the same nostril.
