Journal ArticleDOI
Taste-olfactory convergence, and the representation of the pleasantness of flavour, in the human brain
Ivan E. de Araujo,Edmund T. Rolls,Morten L. Kringelbach,Morten L. Kringelbach,Francis McGlone,Nicola Phillips +5 more
TL;DR: An event‐related fMRI study investigates where in the human brain these interactions between taste and odour stimuli (administered retronasally) may be realized, and provides evidence on the neural substrate for the convergence of taste and olfactory stimuli to produce flavour in humans.
Journal ArticleDOI
Different representations of pleasant and unpleasant odours in the human brain.
Edmund T. Rolls,Morten L. Kringelbach,Morten L. Kringelbach,Ivan E. de Araujo,Ivan E. de Araujo +4 more
TL;DR: The results suggest that there is a hedonic map of the sense of smell in brain regions such as the orbitofrontal cortex, and these results have implications for understanding the psychiatric and related problems that follow damage to these brain areas.
Journal ArticleDOI
Cognitive Modulation of Olfactory Processing
Ivan E. de Araujo,Edmund T. Rolls,Edmund T. Rolls,Maria Inés Velazco,Christian Margot,Isabelle Cayeux +5 more
TL;DR: In an event-related fMRI design, it was shown that the rostral anterior cingulate cortex (ACC)/medial orbitofrontal cortex (OFC) was significantly more activated by the test stimulus and by clean air when labeled "cheddar cheese" than when labeling "body odor," and the activations were correlated with the pleasantness ratings.
Journal ArticleDOI
A Neural Circuit for Gut-Induced Reward.
Wenfei Han,Wenfei Han,Luis A. Tellez,Matthew H. Perkins,Isaac O. Perez,Taoran Qu,Jozélia G. Ferreira,Jozélia G. Ferreira,Tatiana L. Ferreira,Tatiana L. Ferreira,Daniele Quinn,Zhong-Wu Liu,Xiao-Bing Gao,Melanie Maya Kaelberer,Diego V. Bohórquez,Sara J. Shammah-Lagnado,Guillaume de Lartigue,Ivan E. de Araujo +17 more
TL;DR: The findings establish the vagal gut-to-brain axis as an integral component of the neuronal reward pathway and suggest novel vagal stimulation approaches to affective disorders.
Journal ArticleDOI
Food Reward in the Absence of Taste Receptor Signaling
Ivan E. de Araujo,Albino J. Oliveira-Maia,Albino J. Oliveira-Maia,Tatyana D. Sotnikova,Raul R. Gainetdinov,Marc G. Caron,Miguel A. L. Nicolelis,Sidney A. Simon +7 more
TL;DR: In this paper, the same brain reward circuitry that is responsive to palatable rewards also encodes metabolic value independently of taste signaling, showing that calorie rich nutrients can directly influence brain reward circuits that control food intake independently of palatability or functional taste transduction.
