Cortical taste activity in response to sucrose and sweeteners solutions: a study using gustatory evoked potential

2016

Introduction: Sweeteners are widespread in overweight or diabetic patients because of their high sweetening power and their light effect on glycaemia. Sweeteners effects on cortical activity, reflecting both cortical analysis and gustatory signalization pathway, are not well known. We observed previously that gustatory evoked potentials (GEPs) in response to sucrose varied in latency and/or in amplitude with sucrose concentration of the solution, the pleasantness of taste and the feeding status. The aim was to compare the gustatory cortical activity by recording GEPs in response to sucrose, aspartame and stevia solutions.Methods: Twenty healthy non-smoker adult volunteers were included (mea…

Etude du contrôle hédonique de la prise alimentaire par l'analyse des potentiels évoqués gustatifs

2016

Hedonic control of food intake has been studied using neurophysiological investigations in animals and functional imaging in humans. Gustatory evoked potentials (GEPs), a higher time resolution technique than functional imaging, have never been used for this purpose. The first aim of this thesis was to establish a reliable recording of GEPs in humans, in response to a sapid stimulus. The second aim was to determine the GEPs modifications according to the hedonic value of food intake. GEPs recording was performed in response to an intermittent stimulation of a sapid solution in more than 100 young healthy subjects. The comparisons between cerebral recordings in response to water or paraffin …
