Figure 1: Exemplary flow diagram of the study. At first individual test recognitions thresholds to the four tastes were determined in random order in a subject on four separate days (a–d). Then the volunteer entered the experimental phase of the study, where on four separate days (w–z) EGG and ECG recordings were performed in the interdigestive state during a 30-min basal period, a 30-min stimulation with one of the four tastes applied in random order, a 30-min postexposure period. After completion of the recordings, the volunteer rated the stimulation-related sensations in three categories: displeasure/pleasure (score ranging from −10 to 10 points), intensity (0 to 10 points), and nausea feeling (0 to 10 points) with the use of VAS
