An intrinsic association between olfactory identification and spatial memory in humans

Nature Communications, 2018
Olfaction, the sense of smell, may have originally evolved to aid navigation in space, but there is no direct evidence of a link between olfaction and navigation in humans.

Current Knowledge on Chemosensory-Related Candidate Molecules Potentially Involved in Tick Olfaction via Haller’s Organ

Insects, 2023
Ticks are obligatory hematophagous ectoparasites and vectors of many animal and human pathogens. Chemosensation plays a significant role in tick communication with their environment, including seeking out blood meal hosts.

Associations Between Multiple Chemosensory Dysfunction and Cognition

International Forum of Allergy &Rhinology, EarlyView.
Key Points This study supports the association between chemosensory dysfunction and cognition. We introduce methods of assessing trigeminal function with the Medoc TSA‐II thermoprobe. Our results identify an association between subjective trigeminal dysfunction and cognition.

Sniffing out cognitive decline in patients with and without evidence of dopaminergic deficit

Clinical Parkinsonism & Related Disorders, 2019
Background: Depletion of dopamine is a major neuropathological feature of Parkinson's disease; however, 15% of patients with parkinsonian motor symptoms have neuroimaging evidence of intact dopaminergic function.

Poor olfaction and pneumonia hospitalisation among community-dwelling older adults: a cohort study

The Lancet. Healthy Longevity, 2021
Summary: Background: Poor olfaction is common in older adults and might signify broader health implications beyond its role in neurodegeneration. We aimed to evaluate the association of poor olfaction and the risk of any, first-ever, and recurrent ...

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

Advanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Intrinsically Self-renewing Neuroprogenitors From the A/J Mouse Spiral Ganglion as Virtually Unlimited Source of Mature Auditory Neurons

Frontiers in Cellular Neuroscience, 2020
Nearly 460 million individuals are affected by sensorineural hearing loss (SNHL), one of the most common human sensory disorders. In mammals, hearing loss is permanent due to the lack of efficient regenerative capacity of the sensory epithelia and spiral

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)

The Anatomical Record, EarlyView.
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

Olfaction in Eating Disorders and Abnormal Eating Behaviour: A Systematic Review

Frontiers in Psychology, 2015
The study provides a systematic review that explores the current literature on olfactory capacity in abnormal eating behavior to present a basis for discussion on whether research in olfaction in eating disorders may offer additional insights with regard
