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 …
Gustatory evoked cortical activity in humans in response to saccharin stimuli
2014
National audience; Introduction/Objectives: Gustatory Evoked Potentials (GEP) can be detected in response to an intermittent stimulation of the gustatory receptors by a primary flavour. Contrary the other evoked cortical potentials (visual, auditory or sensory), GEP have not been extensively studied due to their recording heterogeneity. Our aim was to establish a reliable recording of GEP in Humans. Methods: Voluntary and healthy subjects were included in this experiment. A saccharin solution with several concentrations (5, 10 or 20g per 100mL) was used as the gustatory stimulus. Each session was performed on a different day, with an interval of at least 2 hours after eating or drinking. Co…
