Olfactory and Sensory Function Studies
Research Guide
What is Olfactory and Sensory Function Studies?
Olfactory and Sensory Function Studies is a research cluster examining olfactory dysfunction, its links to COVID-19, neurological effects, neural processing in the olfactory system, and consequences for quality of life, encompassing anosmia, olfactory receptors, pheromones, taste disorders, and sensory roles in health and disease.
This field includes 89,345 published works on topics such as olfactory dysfunction and its association with COVID-19. Studies address anosmia, olfactory receptors, pheromones, taste disorders, and neurological implications. Research also covers neural processing and impacts on quality of life.
Topic Hierarchy
Research Sub-Topics
Olfactory Dysfunction in COVID-19
Researchers examine the prevalence, mechanisms, and recovery trajectories of anosmia and parosmia associated with SARS-CoV-2 infection. Studies include longitudinal assessments, viral entry via olfactory epithelium, and therapeutic interventions.
Olfactory Receptor Genetics
This area investigates the genomic structure, evolution, and polymorphisms of the olfactory receptor gene family in humans and model organisms. Research links genetic variations to odor detection thresholds and perceptual differences.
Central Olfactory Processing
Neuroimaging and electrophysiological studies map neural circuits in piriform cortex, orbitofrontal cortex, and amygdala involved in odor identification and discrimination. Focus includes plasticity, multisensory integration, and cognitive influences.
Anosmia Pathophysiology
Investigators study conductive, sensorineural, and mixed causes of smell loss, including sinonasal disease, trauma, and neurodegenerative conditions. Research evaluates diagnostic psychophysical tests and olfactory training efficacy.
Human Pheromone Effects
Studies explore chemosensory signals like androstadienone and estratetraenol influencing mood, attraction, and social behavior via vomeronasal or main olfactory pathways. Behavioral and fMRI experiments test subliminal responses.
Why It Matters
Olfactory and Sensory Function Studies document connections between smell loss and major health events like COVID-19, as explored in "Long COVID: major findings, mechanisms and recommendations" (2023), which details persistent anosmia among long COVID symptoms affecting millions worldwide. The discovery of odorant receptors in "A novel multigene family may encode odorant receptors: A molecular basis for odor recognition" by Buck and Axel (1991) established the genetic foundation for smell detection, enabling advances in diagnosing sensory deficits. These insights support clinical assessments of neurological health and quality of life, with sensory evaluation methods from "Sensory Evaluation Techniques" by Meilgaard et al. (2006) applied in food science and medical testing to quantify taste and smell impairments.
Reading Guide
Where to Start
"A novel multigene family may encode odorant receptors: A molecular basis for odor recognition" by Buck and Axel (1991), as it provides the foundational molecular understanding of the olfactory system essential for grasping dysfunction studies.
Key Papers Explained
"A novel multigene family may encode odorant receptors: A molecular basis for odor recognition" by Buck and Axel (1991) lays the genetic groundwork for odor detection, which connects to clinical dysfunction in "Long COVID: major findings, mechanisms and recommendations" by Davis et al. (2023) detailing anosmia persistence. "Sensory Evaluation Techniques" by Meilgaard et al. (2006) builds on this by offering practical testing methods for olfactory and taste impairments. "The Neural Basis of Decision Making" by Gold and Shadlen (2007) extends to how sensory inputs like smell influence neural commitment.
