DOI: 10.1002/cne.25434
Abstract: Circuit operations of the olfactory bulb are modulated by higher order projections from multiple regions, many of which are themselves targets of bulbar output. Multiple glutamatergic regions project to the olfactory bulb, including the anterior… read more here.

Abstract: Perceptual constancy requires the brain to maintain a stable representation of sensory input. In the olfactory system, activity in primary olfactory cortex (piriform cortex) is thought to determine odour identity1-5. Here we present the results… read more here.

DOI: 10.1111/nan.12423
Abstract: Alzheimer's disease (AD) is characterized by cholinergic dysfunction and deposition of β‐amyloid (Aβ) plaques and tau neurofibrillary tangles (NFTs) in the brain. Olfactory abnormalities often precede cognitive symptoms in AD, indicating early involvement of pathology… read more here.

DOI: 10.7554/elife.71238
Abstract: Animals use olfactory receptors to navigate mates, food, and danger. However, for complex olfactory systems, it is unknown what proportion of primary olfactory sensory neurons can individually drive avoidance or attraction. Similarly, the rules that… read more here.
