For some taxa, such as species in the order Carnivora, chemical signals are known to provide a critical mode of communication, although they are still poorly understood compared to other signal modalities. Here, we review the literature to identify and categorise potential chemical signals within the Carnivora with a view to determining commonalities based on sex, taxon, and function. Data were drawn from 112 publications, dating from 1896-2021. Of the 1,532 discrete chemicals identified, 169 were detected in >5 species, with 58 found in ≥10 species. However, multiple different names were often used to report the same compound, reducing the transparency of the literature. 252 chemicals were identified as biomarkers, i.e., associated with specific behavioural contexts (dominance hierarchy, appeasement, agonistic, etc.) or specific demographic traits (age, sex, etc.). Few studies established a causal link between these biomarkers and behavioural or physiological changes, so only a few could be definitively described as behaviourally functional bioactive signals. We found high variability concerning which species, chemicals, and sources were represented in the literature, which could potentially lead to a perceptual bias in the relative importance of certain chemicals. Finally, we propose a method for standardised reporting of chemical signals and suggest that future work should focus on more consistent expansion of the range of species, products, and chemical types analysed, so that the phylogenetic relationship of chemical signals across taxa can be determined.</p>","PeriodicalId":9771,"journal":{"name":"Chemical Senses","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144246656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we report on several psychophysical experiments of citric acid and citrate mixtures. A total of 206 pre-screened frequent consumers of sour foods and/or beverages (i.e., at least once a month) were recruited for this study. Participants rated attribute intensities on general Labeled Magnitude Scales for aqueous equimolar mixtures of varying citric acid and citrate ratios [monosodium citrate (n = 51 participants), disodium citrate (n = 50), trisodium citrate (n = 55), tripotassium citrate (n = 50)], each at three different concentrations. Results revealed that variations in total concentration, amount of citric acid in solution, and type of citrate affected sourness perception and related attributes. Specifically, the number of counterions (i.e., 1, 2, 3 sodium ions) significantly affected sourness, puckering, and drying. The effect of the counterion type (i.e., sodium and potassium) also affected sourness and saltiness. These differences can be attributed to the chemical structures and the protonation states of the mixtures. Additionally, pH measurements revealed the same sourness levels were achieved at different pH levels. From this finding, solutions can be formulated to provide the same perceived sourness at a higher pH level.</p>","PeriodicalId":9771,"journal":{"name":"Chemical Senses","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144246658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when studying the ontogeny of olfactory abilities, not all behaviors are expressed at every age making the longitudinal comparisons difficult. Odor-evoked respiratory responses, which are unlearned and do not require complex motor coordination, may serve as sensitive measures of olfactory abilities throughout ontogeny. Using a non-invasive measure of respiration in an olfactory perceptual paradigm, we assessed odor-evoked respiratory responses in a model of congenital blindness at 3 ages, infant, juvenile and adult, in the same mice and in both males and females. We demonstrated the differential outcome of two respiratory parameters (i.e. frequency and amplitude) in a mouse model of congenital blindness. We showed that blind mice have similar olfactory abilities than sighted mice throughout ontogeny but display enhanced sniffing frequency and amplitude, starting at the juvenile age for the latter one, that may help them better explore their environment. We also demonstrated that respiratory frequency is a robust index of age and of olfactory detection, habituation and discrimination at all ages. On the other side, respiratory amplitude does not provide a proxy of olfactory performance at all ages, however, it does highlight differences between sexes and phenotypes associated with visual deprivation. To conclude, our data highlight that respiratory parameters can be used as a complementary approach to assess olfactory performance throughout development and provide an index of olfactory plasticity.</p>","PeriodicalId":9771,"journal":{"name":"Chemical Senses","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144246657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absence of standardized methods to assess oral somatosensory perception has led to a lack of consensus regarding the relationship between taste and trigeminal sensations. While some studies reported lower trigeminal perception in taste disorders, others did not confirm this correlation. In order to analyze somatosensation in quantitative and qualitative taste problems, 28 patients (21 females, mean age 59.2 years) with taste disturbance and 32 participants (20 females, mean age 42.3 years) with normogeusia identified 3D shapes and letters, sized from 2 to 18 mm, with the anterior part of their tongue, in a threshold test. Additionally, participants rated the intensity of increasing amounts of chili. Gustatory and olfactory functions were also tested. Analyses revealed that patients with taste dysfunction had significantly higher thresholds for lingual tactile sensitivity compared to controls (p < 0.001). Moreover, patients rated the intensity of chili significantly lower than controls (p < 0.001), particularly at higher concentrations. Oral stereognosis threshold scores were negatively correlated with gustatory and olfactory functions, and decreased with increasing age, while intensity for chili correlated with taste scores (p ≤ 0.009). The findings of this study suggest that taste dysfunction is associated with low oral mechanosensory and chemesthetic functions.

While olfactory dysfunction can impact physical, mental, and psychosocial well-being, there has been little research on olfaction during pregnancy and postpartum, nor the impact of SARS-CoV-2 infection on olfaction while pregnant. Therefore, the primary study aims are to evaluate olfaction in the postpartum period and determine the impact of antecedent SARS-CoV-2 infection. We recruited two cohorts of postpartum women, those with a history of SARS-CoV-2 infection before or during pregnancy (COVID cohort; n = 109) and those without (non-COVID cohort; n = 226), and evaluated their olfaction during the postpartum period by administering the University of Pennsylvania Smell Identification Test. Participants were queried about demographics, past SARS-CoV-2 infections, self-reported sense of smell (both in overall ability to smell and for the presence of qualitative smell issues such as parosmia and phantosmia), and perceived cause of smell loss, if any. We found significantly fewer postpartum women with normosmia capabilities in both COVID (27%) and non-COVID (46%) cohorts compared to normative data for aged-matched (30-39 years) women (83%). Women in the non-COVID cohort had significantly higher UPSIT scores and mean subjective olfaction ratings than those in the COVID cohort (95% CI [0.77,2.41] and 95% CI [-0.83,7.34], respectively).

To understand the biological basis of liking and disgust, it is crucial to establish an animal model that allows for quantitative estimation of liking and disgust in response to multimodal stimuli. The only readout shared by many species, including humans, for liking and disgust, has been taste reactivity. However, readouts of non-taste stimuli-induced emotions remain unestablished. Here, we show that intraoral administration of capsaicin, a chemosomatosensory stimulus, elicits orofacial and bodily reactions in male mice similar to those observed in taste reactivity. Capsaicin-induced liking reactions at low concentrations and disgust reactions at high concentrations. Capsaicin-induced disgust reactions consisted of various reactions, including gape and forelimb flail, with the proportion of each reaction among the disgust reactions being similar to that induced by bitter and sour stimuli. These findings indicate that orofacial and bodily reactions, defined as taste reactivity, are elicited not only by taste stimuli but also by intraoral chemosomatosensory stimuli.
