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…
