  • Acquired Olfactory Dysfunction in Children and Adolescents: A Systematic
           Review of the Literature
    • Authors: Schriever V; Gellrich J, von der Hagen M, et al.
      Pages: 571 - 581
      Abstract: Olfactory function can be influenced by many factors and olfactory dysfunction is associated with several diseases. But even considering this, the causes of acquired olfactory dysfunction in children are not well understood. This review was conducted to gain an overview of the etiologies of acquired olfactory dysfunction in a pediatric population. Studies were identified using a predefined literature search, including studies if patients were ≤18 years of age and results of psychophysical olfactory testing were reported. A total of 44 articles met the inclusion criteria for this review and were included in the qualitative analysis. The influence of 6 disease groups on olfactory function in children was observed (otorhinolaryngology, traumatic brain injury, oncology, psychiatric diseases, environmental factors, and other diseases). The current literature is convincing that diseases in the otorhinolaryngology group and traumatic brain injury can lead to acquired olfactory dysfunction, whereas according to the current literature, the role of other influencing factors such as most psychiatric disorders remains uncertain. A number of diseases and circumstances affect olfactory function in children and may cause acquired olfactory dysfunction in this age group. Nevertheless, more research is needed to better understand the causes of acquired olfactory dysfunction in children. Future research should have the goal of early diagnosis and, if possible, early treatment of the condition to prevent a negative impact of olfactory dysfunction on children and adolescents.

  • Automated analysis of breathing waveforms using BreathMetrics: a
           respiratory signal processing toolbox
    • Authors: Noto T; Zhou G, Schuele S, et al.
      Pages: 583 - 597
      Abstract: Nasal inhalation is the basis of olfactory perception and drives neural activity in olfactory and limbic brain regions. Therefore, our ability to investigate the neural underpinnings of olfaction and respiration can only be as good as our ability to characterize features of respiratory behavior. However, recordings of natural breathing are inherently nonstationary, nonsinusoidal, and idiosyncratic making feature extraction difficult to automate. The absence of a freely available computational tool for characterizing respiratory behavior is a hindrance to many facets of olfactory and respiratory neuroscience. To solve this problem, we developed BreathMetrics, an open-source tool that automatically extracts the full set of features embedded in human nasal airflow recordings. Here, we rigorously validate BreathMetrics’ feature estimation accuracy on multiple nasal airflow datasets, intracranial electrophysiological recordings of human olfactory cortex, and computational simulations of breathing signals. We hope this tool will allow researchers to ask new questions about how respiration relates to body, brain, and behavior.

  • Semantic Congruence Alters Functional Connectivity during Olfactory-Visual
           Perception
    • Authors: Sijben R; Hoffmann-Hensel S, Rodriguez-Raecke R, et al.
      Pages: 599 - 610
      Abstract: Previous research has shown that humans struggle to interpret multiple perceptual signals when the information provided by these signals is incongruent. In the context of olfactory-visual integration, behavioral and neuronal differences in response to congruent and incongruent stimulus pairs have been established. Here, we explored functional connectivity of the human brain with regard to the perception of congruent and incongruent food stimuli. Participants were simultaneously presented olfactory and visual stimuli of 4 different food objects, 2 healthy and 2 unhealthy objects. Stimulus pairs were grouped into “congruent” (olfactory and visual presentation of the same object), “semi-congruent” (stimuli of similar “healthiness”), and “incongruent” (healthy-unhealthy stimulus combination). Using functional magnetic resonance imaging and psychophysiological interaction (PPI) analyses, we revealed part of a neural network, the nodes of which show differential connectivity depending on the level of congruency of the presented stimulus combinations. This network relies strongly on, mostly left, inferior frontal gyrus. The analysis of such network transcends standard subtractive designs and indicates the need for more detailed formulations of neuronal models and increased specificity in functional imaging.

      Pages: 611 - 616
      Abstract: The olfactory and trigeminal systems are intimately connected as most odorants stimulate both sensory systems. They interact by mutually suppressing and enhancing each other. However, the location and the degree of their interaction remain unclear. One method to test sensitivity in the trigeminal system is the odor localization task: when an odorant is presented to one nostril, we are able to localize the stimulated nostril only if the odorant stimulates the trigeminal nerve. Our objective was to evaluate the interaction between olfactory and trigeminal system by measuring the effect of an olfactory co-stimulation on the ability to localize a trigeminal stimulus. More specifically, we evaluated the influence of an olfactory co-stimulation with pure odors (phenyl ethanol, vanillin), presented either ipsilaterally or contralaterally, on the localization of predominantly trigeminal stimuli (mustard oil, eucalyptol). The ipsilateral, but not the contralateral, olfactory co-stimulation with a pure odorant increased the capacity to localize a trigeminal stimulus. These results suggest an interaction between the olfactory and trigeminal systems at peripheral, that is, mucosal, levels.

  • Self-reported Smoking Status, TAS2R38 Variants, and Propylthiouracil
           Phenotype: An Exploratory Crowdsourced Cohort Study
    • Authors: Baker A; Miranda A, Garneau N, et al.
      Pages: 617 - 625
      Abstract: TAS2R38 gene variants, which confer sensitivity to specific bitter tastants (e.g., 6-n-propylthiouracil), have been repeatedly associated with lower alcohol use via greater bitterness perception, but research exploring TAS2R38 variation in relation to smoking shows mixed results. In both, the working hypothesis is that 1 or more copies of the functional allele increases bitterness and may provide a barrier to early use. Such a barrier to initiation may, conceivably, manifest as differential rates of current use across diplotypes. Here, an age-diverse convenience sample (n = 886) of Denver Museum of Nature and Science guests was used to explore cross-sectional relationships between TAS2R38 diplotype, self-reported tobacco use (current, former, never smokers), and a rapid measure of 6-n-propylthiouracil phenotype (bitterness of filter paper discs). TAS2R38 diplotypes were determined by Sanger sequencing. After excluding rare diplotypes, data from 814 participants were analyzed. A mix of current (~10%), former (25%), and never smokers (65%) were included. As expected, there was a relationship between TAS2R38 diplotype and 6-n-propylthiouracil bitterness. However, contrary to our hypothesis, there was no evidence of a relationship between diplotype and smoker status among participants with common TAS2R38 diplotypes. Notably, we observed a relationship between of 6-n-propylthiouracil bitterness and smoking status, but the effect was opposite of what was expected: current smokers perceived higher (not lower) bitterness than never smokers. When all the various factors (diplotype, age, sex, and smoking status) were included in ANOVA, all remained predictive of 6-n-propylthiouracil bitterness. Reasons for greater phenotypic bitterness among current smokers are unknown and merit further study.

  • Impaired Odor Perception in Autism Spectrum Disorder Is Associated with
           Decreased Activity in Olfactory Cortex
    • Authors: Koehler L; Fournel A, Albertowski K, et al.
      Pages: 627 - 634
      Abstract: Autism Spectrum Disorders (ASDs) are characterized by atypical sensory functioning in the visual, tactile, and auditory systems. Although less explored, olfactory changes have been reported in ASD patients. To explore these changes on a neural level, 18 adults with ASD and 18 healthy neurotypical controls were examined in a 2-phase study. Participants were first tested for odor threshold and odor identification. Then, (i) structural magnetic resonance (MR) images of the olfactory bulb were acquired, and (ii) a functional MR imaging olfaction study was conducted. ASD patients exhibited decreased function for odor thresholds and odor identification; this was accompanied by a relatively decreased activation in the piriform cortex. In conclusion, these findings suggest, that the known alterations in olfaction in ASD are rooted in the primary olfactory cortex.

  • The Crystal Structure of Gurmarin, a Sweet Tasteā€“Suppressing Protein:
           Identification of the Amino Acid Residues Essential for Inhibition
    • Authors: Sigoillot M; Brockhoff A, Neiers F, et al.
      Pages: 635 - 643
      Abstract: Gurmarin is a highly specific sweet taste–suppressing protein in rodents that is isolated from the Indian plant Gymnema sylvestre. Gurmarin consists of 35 amino acid residues containing 3 intramolecular disulfide bridges that form a cystine knot. Here, we report the crystal structure of gurmarin at a 1.45 Å resolution and compare it with previously reported nuclear magnetic resonance solution structures. The atomic structure at this resolution allowed us to identify a very flexible region consisting of hydrophobic residues. Some of these amino acid residues had been identified as a putative binding site for the rat sweet taste receptor in a previous study. By combining alanine-scanning mutagenesis of the gurmarin molecule and a functional cell-based receptor assay, we confirmed that some single point mutations in these positions drastically affect sweet taste receptor inhibition by gurmarin.

  • Regional Differences in Taste Responsiveness: Effect of Stimulus and
           Tasting Mode
    • Authors: Colvin J; Pullicin A, Lim J.
      Pages: 645 - 653
      Abstract: Previous studies have shown that there are differences in taste responses between various regions of the tongue. Most of those studies used a controlled “passive” tasting mode due to the nature of investigation. However, food is rarely tasted in a passive manner. In addition, recent studies have suggested that humans can taste maltooligosaccharides (MOS) and that the gustatory detection of MOS is independent of the known sweet receptor. It is unknown whether regional differences in responsiveness to MOS exist. This study was set up to revisit previous work by investigating the effects of tasting mode (“passive” vs. “active”) on regional differences in taste responsiveness to sucrose, monopotassium glutamate (MPG), and quinine, while also investigating potential regional differences in responsiveness to MOS. The stimuli were applied to 1 of 4 target areas, the left and right sides of the front and back of the tongue, using cotton-tipped swabs. In the passive tasting condition, the front of the tongue was found to be more responsive to both sucrose and MOS, but no regional differences were seen for quinine and MPG. In contrast, in the active tasting condition, the back of the tongue was found to be more responsive to quinine and MPG, but no differences were found for sucrose or MOS. These findings indicate that there are regional differences in taste responsiveness between the front and back of the tongue and that regional responsiveness is dependent on stimulus and tasting mode.

  • Postnatal Exposure to Ethanol Increases Its Oral Acceptability to
           Adolescent Rats
    • Authors: Tang J; Youngentob S, Glendinning J.
      Pages: 655 - 664
      Abstract: The aversive flavor of ethanol limits intake by many consumers. We asked whether intermittent consumption of ethanol increases its oral acceptability, using rats as a model system. We focused on adolescent rats because they (like their human counterparts) have a higher risk for alcohol overconsumption than do adult rats following experience with the drug. We measured the impact of ethanol exposure on 1) the oral acceptability of ethanol and surrogates for its bitter (quinine) and sweet (sucrose) flavor components in brief-access lick tests and 2) responses of the glossopharyngeal (GL) taste nerve to oral stimulation with the same chemical stimuli. During the exposure period, the experimental rats had access to chow, water and 10% ethanol every other day for 16 days; the control rats had access to chow and water over the same time period. The experimental rats consumed 7–14 g/day of 10% ethanol across the exposure period. This ethanol consumption significantly increased the oral acceptability of 3%, 6% and 10% ethanol, but had no impact on the oral acceptability of quinine, sucrose or NaCl. The ethanol exposure also diminished responses of the GL nerve to oral stimulation with ethanol, but not quinine, sucrose or NaCl. Taken together, these findings indicate that ethanol consumption increases the oral acceptability of ethanol in adolescent rats and that this increased oral acceptability is mediated, at least in part, by an exposure-induced reduction in responsiveness of the peripheral taste system to ethanol per se, rather than its bitter and sweet flavor components.
