Abstract In response to the coronavirus disease 2019 (COVID-19) pandemic, countries have implemented various strategies reduce and slow spread of in general population. For that restrictions on its population a stepwise manner, monitoring COVID-19 prevalence is importance guide decision when impose new, or abolish old, restrictions. We are here determining whether measures odor intensity large sample can serve as one such measure. Online how intense common household odors perceived symptoms...
Social chemosignaling is a part of human behavior, but how chemosignals transfer from one individual to another unknown. In turn, humans greet each other with handshakes, the functional antecedents this behavior remain unclear. To ask whether handshakes are used sample conspecific social chemosignals, we covertly filmed 271 subjects within structured greeting event either or without handshake. We found that often sniff their own hands, and selectively increase after After gender, increased...
Rules linking patterns of olfactory receptor neuron activation in the nose to activity brain and ensuing odor perception remain poorly understood. Artificially stimulating neurons with electrical currents measuring may uncover these rules. We therefore inserted an electrode into 50 human volunteers applied various for about hour each case. This induced assorted non-olfactory sensations but never once odor. To validate contact path, we used functional magnetic resonance imaging measure...
A common goal in olfaction research is modeling the link between odorant structure and odor perception. Such efforts require large data sets on olfactory perception, yet only a few of these are publicly freely available. Given that individual perception may be informative personal makeup interpersonal relationships, we hypothesized people would gladly provide perceptual estimates context an odor-based social network. We developed web-based infrastructure for such network called SmellSpace...
Sniffing a molecule emitted from baby heads makes men less aggressive yet women more aggressive.
Key to curtailing the COVID-19 pandemic are wide-scale screening strategies. An ideal screen is one that would not rely on transporting, distributing, and collecting physical specimens. Given olfactory impairment associated with COVID-19, we developed a perceptual measure of olfaction relies smelling household odorants rating them online.
Mammalian olfaction and reproduction are tightly linked, a link less explored in humans. Here, we asked whether human unexplained repeated pregnancy loss (uRPL) is associated with altered olfaction, particularly olfactory responses to body-odor. We found that whereas most women uRPL could identify the body-odor of their spouse, control not. Moreover, rated perceptual attributes men's differently from controls. These pronounced differences were accompanied by an only modest albeit significant...
ABSTRACT In response to the COVID-19 pandemic, countries have implemented various strategies reduce and slow spread of disease in general population. For that restrictions on its population a step-wise manner, monitoring prevalence is importance guide decision when impose new, or abolish old, restrictions. We are here determining whether measures odor intensity large sample can serve as one such measure. Online how intense common household odors perceived symptoms were collected from 2440...
All primates, including humans, engage in self-face-touching at very high frequency. The functional purpose or antecedents of this behaviour remain unclear. In hybrid review we put forth the hypothesis that subserves self-smelling. We first data implying humans touch their own face then detail evidence from one study implicated an olfactory origin for behaviour: This consists significantly increased nasal inhalation concurrent with self-face-touching, and predictable increases decreases as a...
Abstract Body-volatiles can effectively trigger or block conspecific aggression in terrestrial mammals. Here we tested whether hexadecanal (HEX), a human body-volatile implicated as mammalian-wide social cue, impacts aggression. Using validated behavioural paradigms, observed remarkable dissociation: sniffing HEX blocked men, but triggered women. Next, using functional brain imaging, uncovered pattern of activity mirroring behaviour: In both men and women, increased the left angular gyrus,...
Abstract Key to curtailing the COVID-19 pandemic are wide-scale testing strategies 1,2 . An ideal test is one that would not rely on transporting, distributing, and collecting physical specimens. Given olfactory impairment associated with 3-7 , we developed a novel measure of perception relies smelling household odorants rating them online. We tested performance this real-time tool in 12,020 participants from 134 countries who provided 171,500 perceptual ratings 60 different odorants....
Abstract Study question Is there a male body-odor associated with unexplained recurrent pregnancy loss (uRPL)? Summary answer The of men from uRPL couples may have different chemical composition than control men. What is known already Recurrent defined as 2-3 consecutive losses, affecting about 1% all couples, and in half them, the reason for losses (uRPL). In our previously published study, we found that women who experienced altered perceptual brain responses to men’s body-odors comparison...
Breathing patterns may inform on health. We note that the sites of earliest brain damage in Parkinson's disease (PD) house neural pace-makers respiration. therefore hypothesized ongoing long-term temporal dynamics respiration be altered PD. applied a wearable device precisely logs nasal airflow over time 28 PD patients (mostly H&Y stage-II) and 33 matched healthy controls. Each participant wore for 24 h otherwise routine daily living. observe significantly PD, where inhalations are longer...
