However, when performed in the standard method, this task takes almost 25 to 30?min to administer and only gives access to few information.The aim of this pilot study was to compare two alternative methods of administering the lateralization task with the standard method in a group of 53 participants (41.6?years; 32 women). Specifically, we compared (1) the standard method of 40 constant stimuli with a duration of 500?ms, (2) a short version of 20 variable stimuli ranging from 200 to 600?ms (different duration method—DD), and (3) an automatic adaptive staircase method where the test adjusts the duration of stimulation according to the participant’s responses (adaptive duration method—AD).Based on the number of correct answers and the thresholds obtained with the automatic staircase method, the average scores for the two alternative methods correlate with the score at the standard method. In addition, both alternative methods are able to discriminate between participants with a high sensitivity and those with a lower sensitivity. Finally, the DD method is significantly shorter in terms of administration time than the other two methods.This pilot study presents two novel methods to evaluate trigeminal sensitivity which each have a specific superiority over the established technique.The DD method cuts testing time in half whereas the AD method provides threshold estimates for individual nostrils.","PeriodicalId":516,"journal":{"name":"Chemosensory Perception","volume":"14 1","pages":"19 - 26"},"PeriodicalIF":1.0,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12078-020-09281-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5569171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For each of the 16 stimuli, participants rated how much they liked, how disgusting and how intense they perceived each tastant.Contrary to previous findings, higher psychopathic traits were not associated with higher liking ratings for bitter stimuli, but instead associated with higher disgust ratings of bitter stimuli. Moreover, higher psychopathic traits were associated with higher taste intensity ratings, suggesting psychopathy may be associated with increased taste sensitivity.Higher degrees of psychopathic traits are associated with higher disgust ratings of bitter stimuli.The findings suggest that the chemical senses may be another confirmatory method for differentiating those with low and high psychopathic traits.","PeriodicalId":516,"journal":{"name":"Chemosensory Perception","volume":"14 1","pages":"47 - 56"},"PeriodicalIF":1.0,"publicationDate":"2020-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12078-020-09278-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4890719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In turn, in women using oral contraceptives, only at a later time of the month, at a point corresponding to the late luteal phase and shift from post-ovulation to pre-menstruation, was there a decline of 20% (p = 0.002) in olfactory discrimination performance. Moreover, when we reorganized the data from women using oral contraceptives in order to separately assess the contraceptive withdrawal period (the few days off pills), we observed a 23% reduction (p = 0.01) in discrimination accuracy of body odors but not ordinary odorants during this time alone.Women have reduced ability to discriminate body odors during the withdrawal period of oral contraception.If women indeed consider men’s body odor in their mate selections, then the oral contraception withdrawal period may not be the best time to make such decisions.","PeriodicalId":516,"journal":{"name":"Chemosensory Perception","volume":"13 2","pages":"123 - 131"},"PeriodicalIF":1.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12078-019-09273-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4245651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this is not an evidence-based practice, as no literature proves this. The aim of this study was therefore to identify the best palate cleanser to use in sensory evaluation of minty confectionery products.Three chewing gums with different cooling intensity were chewed for 3?min by a trained panel and evaluated for overall cooling, nose tingling, mouth burning, minty aroma, and sweetness. After the sample tasting, the following different palate cleansers were proposed: low-salt breadstick, whole milk, milk chocolate, white chocolate, and sunflower oil, compared with the resting time (control). The residual sensations were measured for the next 15?min.Breadstick and seed oil are the most effective palate cleansers on overall cooling carry-over. White chocolate seems to be effective on mint aroma, but this is likely to be due to its strong flavour, masking other perceptions. Moreover, both white and milk chocolates affect negatively the sweetness perception, by increasing it soon after the consumption, and even impacting on the next sample evaluation.None of the palate cleansers were able to fully re-establish the oral environment after 15?min. Therefore, further studies on combinations, or on repeated use of the same palate cleanser, are proposed.The use of an effective palate cleanser can reduce the time for product testing and increase data precision. Finding a proper palate cleanser for minty products is a strategy to optimise sensory evaluations in confectionery industry.","PeriodicalId":516,"journal":{"name":"Chemosensory Perception","volume":"13 2","pages":"106 - 118"},"PeriodicalIF":1.0,"publicationDate":"2019-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12078-019-09271-x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4628241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from 213 subjects were analyzed. They were aged 22–25, completed 3-Tesla structural brain scan, and were asked to taste a bitter solution (0.001 M quinine) and rate the perceived intensity with a general Labelled Magnitude Scale. The age-adjusted taste intensity rating was used for the current analysis. Voxel-based morphometry (VBM) using CAT12 toolbox implemented in SPM12 was conducted with the default procedures and settings. Whole brain analysis was performed at a threshold of cluster p < 0.05, familywise error corrected (FWE), with a primary cluster-forming threshold of uncorrected voxel p < 0.001.Voxel-wise GMV was significantly correlated to taste intensity rating in the right angular gyrus. OFC was insignificant even with a more liberal threshold of uncorrected voxel p < 0.001.The current results were again different from previously published reports. This might be due to heterogeneous population, data processing, and analytical methods.At the current stage, the morphometric finding from brain imaging is not yet a simple and reliable biomarker for assessing taste intensity perception.","PeriodicalId":516,"journal":{"name":"Chemosensory Perception","volume":"13 2","pages":"119 - 122"},"PeriodicalIF":1.0,"publicationDate":"2019-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12078-019-09272-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4704533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a further behavioral study using 12 chronic insomniacs, we investigated whether the commercial odors showed effects on sleep during a double-blind, randomized home evaluation.In the neuroimaging, the odors were related to activation of olfactory-relevant areas, such as the orbitofrontal cortex, and we found positive connectivity between the piriform cortex and the hippocampus, amygdala, insula, and middle cingulate cortex. Deep Sleep specifically activated the superior temporal gyrus, whereas Oriental activated the caudate. Further, these commercial odors showed some beneficial impact on sleep.The perceptual and neural impacts of the commercial odors showed that olfactory stimulation can potentially aid sleep and modify affective processes in a number of ways.The present work opens up opportunities for further investigations into how different odors may lead to specific behavioral and physiological modifications, such as their impact on sleep and well-being, which may provide non-pharmacological alternative approaches.","PeriodicalId":516,"journal":{"name":"Chemosensory Perception","volume":"13 2","pages":"93 - 105"},"PeriodicalIF":1.0,"publicationDate":"2019-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12078-019-09269-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4242082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was a 25-min rest interval between two fMRI runs with identical stimulation paradigms with two odors, as phenylethyl alcohol (PEA) and isovaleric acid (IVA), and the two odors were released alternately.There was a similar activation pattern in regions of primary and secondary olfactory cortex induced by odors of both valences, especially by negative odor. Weakened activation of the brain is responsive to repeated both pleasant and unpleasant smell. Nevertheless, the repeated unpleasant odor has a more intimate relationship with the piriform cortex, amygdala, and hippocampus.We conclude that asymmetric brain activation in response to repeated odorant stimulation depended on valences and that the unpleasant odor can evoke more negative emotion and profound memory.We explore the central processing about repeated olfactory information applied fMRI for the first time, revealing asymmetric brain activation in response to repeated odors of pleasantness and unpleasantness.","PeriodicalId":516,"journal":{"name":"Chemosensory Perception","volume":"13 1","pages":"84 - 91"},"PeriodicalIF":1.0,"publicationDate":"2019-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12078-019-09270-y","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4111399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
