Biochemical Studies of Taste Sensation
Large numbers of taste buds are distributed over the body surface of the channel catfish Zctalurus punctatus, with the barbels having an especially high density. L-Alanine, as well as certain other amino acids, are taste stimuli in this animal. Epithelial tissue obtained by gentle scraping of the barbel surface was fractionated by differential centrifugation. A sedimentable fraction (P2) was pr...
متن کاملIntravital Microscopic Interrogation of Peripheral Taste Sensation
Intravital microscopy is a powerful tool in neuroscience but has not been adapted to the taste sensory organ due to anatomical constraint. Here we developed an imaging window to facilitate microscopic access to the murine tongue in vivo. Real-time two-photon microscopy allowed the visualization of three-dimensional microanatomy of the intact tongue mucosa and functional activity of taste cells ...
متن کاملMechanisms for Taste Sensation of Carbonation
Mechanisms for Taste Sensation of Carbonation David Yarmolinsky Carbonation, or the presence of carbon dioxide (CO2) dissolved in solution, is a commonly encountered feature of beverages in the contemporary human diet. While the popularity of carbonation may be attributed to its distinct sensory qualities, the specific orosensory pathways mediating CO2 detection in mammals have not previously b...
متن کاملHedgehog pathway blockade with the cancer drug LDE225 disrupts taste organs and taste sensation.
Taste sensation on the anterior tongue requires chorda tympani nerve function and connections with continuously renewing taste receptor cells. However, it is unclear which signaling pathways regulate the receptor cells to maintain chorda tympani sensation. Hedgehog (HH) signaling controls cell proliferation and differentiation in numerous tissues and is active in taste papillae and taste buds. ...
متن کاملAssociations between taste genetics, oral sensation and alcohol intake.
Alcohol produces a range of oral sensations, some of which have been shown to vary with the perceived bitterness of 6-n-propylthiouracil (PROP), one marker for genetic variation in taste. Some studies report that offspring of alcoholics are most likely to be PROP nontasters [Physiol. Behav. 51 (1992) 1261; Physiol. Behav. 64 (1998) 147], yet others report the offspring as more responsive to sod...
