Aim of the present study was to investigate laterality of the gustatory system in the human brain for the taste qualities elicited by MSG (monosodium glutamate) and NaCl (sodium chloride). A total of 23 subjects participated in a block-design functional magnetic resonance imaging (fMRI) study. Liquid stimuli were presented at supra-threshold concentrations(More)
In this study, we report gustatory event-related potentials in response to stimulation with monosodium glutamate (MSG) and salt (NaCl). We investigated differences in event-related potential related to stimulus quality, stimulus concentration, cortical topography, and participants' sex. Our results showed that amplitudes P1N1 and N1P2 were significantly(More)
In this study, we investigated inter-individual differences in sensitivity to mono-sodium glutamate (MSG) and elucidated the familiarity to umami taste in two European populations. The study consisted of two parts: (1) a survey based on questionnaire and (2) psychophysical screening for inter-individual variation of MSG sensitivity. The psychophysical tests(More)
Burning mouth syndrome (BMS) is characterized by a burning sensation in the mouth, usually in the absence of clinical and laboratory findings. Latest findings indicate that BMS could result from neuropathic trigeminal conditions. While many investigations have focused on the periphery, very few have examined possible central dysfunctions. To highlight(More)
BACKGROUND One of several probable causation theories of Parkinson disease postulates that brain tissue cannot generate sufficient levels of various growth factors required to sustain the viability of dopamine-producing nerve cells in the presence of as yet unknown toxic factors. The study reported here evaluates the ability of externally applied growth(More)
AIM The identification of umami taste among people is extremely variable. Based on functional magnetic resonance imaging (fMRI) the aim of this study was to investigate changes of brain activation in participants before and after they were familiarized with this peculiar taste. MATERIAL AND METHOD A total of 10 healthy, right-handed subjects (7 women,(More)
Chemosensory function, burning sensations in the tongue (BST), halitosis, saliva secretion, and oral health-related quality of life (OHRQoL) were investigated in patients with primary Sjögren's syndrome (pSS). In 31 patients with pSS and 33 controls, olfactory and gustatory functions were evaluated. Self-reported complaints of dysgeusia, BST, and halitosis(More)
A comprehensive evaluation of oral and ocular symptoms and findings in primary Sjögren's syndrome (pSS) patients may provide valuable information for management. Medical history was obtained from female pSS patients, and sex- and age-matched non-SS patients with sicca symptoms (non-SS sicca controls) as well as healthy subjects without sicca complaints(More)
