Olfactory training – Thirteen years of research reviewed

Neuroscience & Biobehavioral Reviews, Год журнала: 2022, Номер 141, С. 104853 - 104853

Опубликована: Сен. 5, 2022

The sense of smell is interrelated with psychosocial functioning. Olfactory disorders often decrease quality life but treatment options for people olfactory loss are limited. Additionally, accompanies and precedes psychiatric neurodegenerative diseases. Regular, systematic exposure to a set odors, i.e., training (OT) has been offered rehabilitation the in clinical practice. As signals from bulb directly projected limbic system it also debated whether OT might benefit psychological functioning, mitigate cognitive deterioration or improve emotional processing. In this review we synthesize key findings on utility practice highlight molecular, cellular, neuroanatomical changes accompanying recovery as well experimental animal models. We discuss how its modifications have used interventions aiming support functions well-being. delineate main methodological challenges research suggest areas requiring further scientific attention.

Intrinsic and extrinsic factors affecting axillary odor variation. A comprehensive review

Physiology & Behavior, Год журнала: 2023, Номер 270, С. 114307 - 114307

Опубликована: Июль 28, 2023

Humans produce odorous secretions from multiple body sites according to the microbiomic profile of each area and types secretory glands present. Because axilla is an active, odor-producing region that mediates social communication via sense smell, this article focuses on biological mechanisms underlying creation axillary odor, as well intrinsic extrinsic factors likely impact odor determine individual differences. The list discussed includes sex, age, ethnicity, emotions, personality, include dietary choices, diseases, climate, hygienic habits. In addition, we also draw attention gaps in our understanding factor, including, for example, topical areas such effect climate variation. Fundamental challenges emerging research opportunities are further outlined discussion. Finally, suggest guidelines best practices based reviewed herein preparatory protocols sweat collection, data analysis, interpretation.

The interactive role of odor associations in friendship preferences

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Апрель 2, 2025

Who we choose to befriend is highly personal, driven by idiosyncratic preferences about other individuals, including sensory cues. How does a person's unique evaluation of others' body odor affect friendship formation? Female participants took part in speed-friending event where they made judgments potential (FP) following 4-minute live interaction. Prior and the event, judged FP these women based solely on diplomatic (including daily perfume/hygiene products) presented worn t-shirts. Participants also facial appearance (a 100-ms presentation portrait photographs). Judgments predicted in-person interactions, beyond predictive ability photograph-based judgments. Moreover, interaction changes second round judgments, suggesting that quality modified olfactory perception. Results were more strongly than global perceiver or target effects. Findings highlight dynamic role ecologically relevant social cues informing as well involvement odor-based associative learning during early stages formation.

Influence of the human body odor compound HMHA on face perception

Perception, Год журнала: 2024, Номер 53(3), С. 180 - 196

Опубликована: Янв. 12, 2024

Body odors convey information about the individuals, but mechanisms are not fully understood yet. As far as human reproduction is concerned, molecules that produced in sexually dimorphic amounts could be possible chemosignals. 3-hydroxy-3-methylhexanoic acid (HMHA) one of them—more typical men. Here, we investigated possibility perception gender and attractiveness faces implicitly influenced by this compound. Clearly feminine, ambiguous clearly masculine were primed with an odor HMHA, a control or air. Based on 100-ms face presentation, 40 raters had to identify face's quickly provide evaluations. tended perceived less pleasant induced lower sniff duration women compared effects HMHA (vs. conditions), found identification associated response time unaffected HMHA. Attractiveness faces, however, increased presence sex-specific manner only for unattractive gender. In sum, study no evidence favor role compound intrasexual competition nor intersexual attraction.
