Patterns of cerebral activation during olfactory and trigeminal stimulations

S Lombion, A Comte, L Tatu, G Brand… - Human brain …, 2009 - Wiley Online Library
It is well known that most odorants stimulate both the olfactory system and the trigeminal
system. However, the overlap between the brain processes involved in each of these …

Time course of odorant-and trigeminal-induced activation in the human brain: an event-related functional magnetic resonance imaging study

PE Billot, A Comte, E Galliot, P Andrieu, V Bonnans… - Neuroscience, 2011 - Elsevier
It is well known that most odorants stimulate the trigeminal system but the time course of the
brain regions activated by these chemical stimulations remains poorly documented …

Functional MRI of regional brain responses to 'pleasant'and 'unpleasant'odors

K Katata, N Sakai, K Doi, H Kawamitsu… - Acta Oto …, 2009 - Taylor & Francis
Conclusions: Our findings demonstrate that functional MRI (fMRI) combined with a
questionnaire is a useful method for studying the neuroanatomy of olfaction. Further studies …

Human brain activation in response to olfactory stimulation by intravenous administration of odorants

A Miyanari, Y Kaneoke, Y Noguchi, M Honda… - Neuroscience …, 2007 - Elsevier

resonance imaging (fMRI) scans in response intravenously instilled thiamine propyl disulfide …

Dissociated representations of pleasant and unpleasant olfacto-trigeminal mixtures: an FMRI study

M Bensafi, E Iannilli, J Poncelet, HS Seo, J Gerber… - PLoS …, 2012 - journals.plos.org
How the pleasantness of chemosensory stimuli such as odorants or intranasal trigeminal
compounds is processed in the human brain has been the focus of considerable recent …

Cross-modal integration of intranasal stimuli: a functional magnetic resonance imaging study

JA Boyle, J Frasnelli, J Gerber, M Heinke, T Hummel - Neuroscience, 2007 - Elsevier
Most odorants, in addition to the olfactory system, also activate the intranasal trigeminal
system. Recent studies have shown that pure trigeminal stimulation activates …

[PDF][PDF] Differences in anosmic and normosmic group in bimodal odorant perception: a functional-MRI study

E Iannilli, T Bitter, H Gudziol, HP Burmeister… - Rhinology, 2011 - academia.edu
So-called bimodal odorants are able to stimulate the intranasal trigeminal system at
relatively low concentrations. Using them as stimuli, the current study focused on the …

Bimodal odor processing with a trigeminal component at sub-and suprathreshold levels

R Pellegrino, E Drechsler, C Hummel, J Warr… - Neuroscience, 2017 - Elsevier
Odors are typically bimodal in nature, interacting with the olfactory and trigeminal systems.
The trigeminal component may be noticed (eg menthol) or perceptually ignored, leading to …

fMRI activation in response to odorants orally delivered in aqueous solutions

B Cerf-Ducastel, C Murphy - Chemical Senses, 2001 - academic.oup.com
During food intake flavor perception results from simultaneous stimulation of the gustatory,
olfactory and trigeminal systems. Olfactory stimulation occurs mainly through the retronasal …
