The aroma and taste of eight different phototrophic microalgae species were investigated compared with five seaweeds to evaluate their potential as flavor ingredients in plant-based seafood alternatives. To assess performance, commercial flavoring products used a reference during the sensory evaluation chemical odor-active taste-active profiles those algae. Stronger odor observed Rhodomonas sal...

The electrical properties of the frog taste cells during gustatory stimulations with distilled water and varying concentrations of NaCl were studied with intracellular microelectrodes. Under the Ringer adaptation of the tongue, two types of taste cells were distinguished by the gustatory stimuli. One type, termed NaCl-sensitive (NS) cells, responded to water with hyperpolarizations and responde...

The perception of the pleasantness of sweet tastes varies widely across individuals. Here, we exploit these differences to isolate brain response to sweet-taste pleasantness while controlling for intensity, quality, and physiological significance. Thirty subjects participated in functional MRI scanning while consuming individually calibrated weak and strong sucrose solutions. All subjects found...

Evidence from both human and animal studies suggests that sensitivity to rewarding stimuli is positively associated with impulsive behaviors, including both impulsive decision making and inhibitory control. The current study examined associations between the hedonic value of a sweet taste and two forms of impulsivity (impulsive choice and impulsive action) in healthy young adults (N = 100). Par...

The ionic mechanism underlying the receptor potential induced by a deionized water stimulus was studied in frog taste cells with conventional microelectrodes. The taste cells located in the proximal portion of the tongue generated a depolarizing receptor potential which averaged 10mV in response to stimulation with deionized water. The cell membrane of the water-sensitive taste cell could be di...
