چکیده

The ability to taste brings us some of the finest things in life: the sweetness of candy, the saltiness of chips, and the sourness of lemonade. We all know it starts on the tongue, but how does it really work? Scientists have discovered that taste comes from a chain reaction that starts with sensitive proteins on your tongue, races through taste buds, enters your nerves, and ends in your brain. One of the most amazing findings is that taste sensitivity varies from person to person. Each of us lives in a unique taste world, making everyone different in the foods they love and hate.

Why is fat so tasty? Chemical reception of fatty acid on the tongue.

Fatty foods are very palatable. Most mammals, including humans, prefer high-fat food to low-fat food. Neuropeptides and neurotransmitters, which are related to the hedonic or aversive response in the brain, are released after a basic tastant (i.e., sweet, sour, salty, bitter or umami) is accepted by the taste receptors in the taste bud cells. In addition, recent evidence suggests that dietary f...

On the specification of taste neurons in the rat tongue.

It is known in mammals that regenerating taste fibers will reform, innervate and maintain new taste buds in characteristic tongue locations--the taste papillae. The ability of non-taste sensory and motor nerve fibers (auriculo-temporal, mylohyoid and hypoglossal nerves) to substitute for a taste (IXth) nerve was evaluated by whole nerve recording and anatomical examination of experimentally inn...

Developmental changes in taste responses from glossopharyngeal nerve in sheep and comparisons with chorda tympani responses.

To learn whether there are developmental changes in salt and acid taste responses from the posterior tongue, we recorded from the glossopharyngeal nerve, which innervates taste buds in circumvallate papillae, in sheep fetuses, lambs and adults. Multifiber responses to NH4Cl, KCl, NaCl, LiCl, citric and hydrochloric acids were expressed as ratios, relative to responses for two standard chemicals...

Development of gustatory organs and innervating sensory ganglia.

Taste function requires neural circuits to transmit gustatory information from taste receptor cells in taste buds, via afferent nerves to the soma of ganglion neurons, and through central ganglion processes into the brainstem. During initial formation, the sensory ganglion neurons have a key situation in establishing receptive fields by extending neurites bidirectionally, to the peripheral tast...

Demonstration of sensory innervation of rat tongue with anterogradely transported horseradish peroxidase.

Wheat germ agglutinin-horseradish peroxidase injected into the petrosal ganglion in rats was transported to the posterior tongue in the glossopharyngeal nerve. Labelled fibers innervated the ipsilateral foliate papilla only, but both ipsi-and contralateral sides of the single circumvallate papilla. Somatosensory fibers in the posterior tongue also were labelled. Label crossed transcellularly fr...
