Freemantle, Alexander W. J.; Stafford, Lorenzo D.; Wagstaff, Christopher R. D.; Akehurst, Lucy

2022 Chemosensory Perception

doi:10.1007/s12078-021-09293-4

IntroductionResearch has provided evidence for the transfer of single emotions including anger, anxiety and happiness through olfactory chemosignals, yet no work has examined the role of odour function in the aggregation of more complex emotional states or in the emotional contagion process. The...

Olfactory Capabilities Towards Food and Non-food Odours in Men and Women of Various Weight Statuses

Mas, Marine; Chabanet, Claire; Sinding, Charlotte; Thomas-Danguin, Thierry; Brindisi, Marie-Claude;

2022 Chemosensory Perception

doi:10.1007/s12078-021-09294-3

IntroductionOlfaction is a sense that is closely linked to food intake and food choices in humans, but its relationship with obesity remains equivocal in the scientific literature: overall olfactory capacities seem poorer in obesity compared to normal weight, but some authors observed that...

Human Oral Sensitivity to and Taste Modulation by 3-Mercapto-2-Methylpentan-1-ol

Wise, Paul M.; Ledyard, Anne

2022 Chemosensory Perception

doi:10.1007/s12078-022-09295-w pmid:35233259

Introduction3-Mercapto-2-methylpentan-1-ol (3 M) is a key onion flavor (aroma), but past sensory work has focused primarily on ortho-nasal presentation. A series of experiments was conducted to characterize human sensitivity to oral 3 M solutions, then determine how 3 M impacts perception of...

Smelling Death, Loving Life: the Impact of Olfactory Chemosignals on Life Satisfaction

Barnett, Michael D.; Mokhtari, Ben K.; Moore, Jenna M.

2022 Chemosensory Perception

doi:10.1007/s12078-022-09297-8

IntroductionPrevious research suggests that putrescine — the chemical compound that gives decomposing organic matter its distinctive odor — may trigger an inborn evolutionary mechanism that prompts individuals to avoid the smell of decay. The purpose of these two experiments was to investigate...

Long-term Olfactory Functions in Patients with Subjective Cognitive Decline and Mild Cognitive Impairment

Novotny, D.; Stögmann, E.; Lehrner, J.

2022 Chemosensory Perception

doi:10.1007/s12078-022-09298-7

IntroductionOlfactory function is known to be impaired in patients with Alzheimer’s disease (AD) as well as in subjective cognitive decline (SCD) and mild cognitive impairment (MCI), which are generally considered at-risk states for developing AD. The aim of the study at hand was to identify...

Differences in Brain Responses to Food or Tastants Delivered with and Without Swallowing: a Meta-analysis on Functional Magnetic Resonance Imaging (fMRI) Studies

Yeung, Andy Wai Kan

2022 Chemosensory Perception

doi:10.1007/s12078-022-09299-6

IntroductionThis study aimed to meta-analyze the functional magnetic resonance imaging (fMRI) data and compare the brain activations from gustatory studies with different stimulus delivery methods.MethodsPublished fMRI studies were included into the analysis if they evaluated the brain responses...

A Nasal Aerodynamics Perspective of Retronasal Olfaction: Rodents vs. Humans

Kim, Kanghyun; Zhao, Kai

2022 Chemosensory Perception

doi:10.1007/s12078-022-09300-2 pmid:37192933

IntroductionOdor perception can be achieved through ortho or retronasal routes, with the latter being an important component of flavor perception. There are significant olfactory differences that exist between rats and humans and by understanding the role of structural differences, further...

Effects of Gender and Age on Self-reported Odor Imagery Ability

Fantin, Luca; Pinzano, Chloé; Rumeau, Cécile; Hossu, Gabriela; Ceyte, Hadrien

2022 Chemosensory Perception

doi:10.1007/s12078-022-09302-0

IntroductionOdor imagery is known to be more difficult than any other modality of sensory imagery. Consequently, wide between-individuals variability can be found in odor imagery ability. Several studies have shown a positive relationship between olfactory performance and odor imagery ability. In...
