Discrete innervation of murine taste buds by peripheral taste neurons.
The peripheral taste system likely maintains a specific relationship between ganglion cells that signal a particular taste quality and taste bud cells responsive to that quality. We have explored a measure of the receptoneural relationship in the mouse. By injecting single fungiform taste buds with lipophilic retrograde neuroanatomical markers, the number of labeled geniculate ganglion cells in...
متن کاملTaste Preference Following Cross-Innervation of Rat Fungiform Taste Buds'
OAKLEY, B. Taste preference following cross-innervation of rat fungiform taste buds. PHYSIOL. BEHAV. 4 (6) 929--933, 1969.-It has been previously demonstrated that cross-innervation of rat taste buds alters some features of the taste input signal to the brain. In the present study the behavioral consequences of these alterations were assessed in a choice situation in which both water and taste ...
متن کاملInnervation of single fungiform taste buds during development in rat.
To determine whether the innervation of taste buds changes during postnatal development, the number of geniculate ganglion cells that innervated single fungiform taste buds were quantified in the tip- and midregions of the tongue of adult and developing rats. There was substantial variation in both the size of individual taste buds and number of geniculate ganglion cells that innervated them. I...
متن کاملEmbryonic taste buds develop in the absence of innervation.
It has been hypothesized that taste buds are induced by contact with developing cranial nerve fibers late in embryonic development, since descriptive studies indicate that during embryonic development taste cell differentiation occurs concomitantly with or slightly following the advent of innervation. However, experimental evidence delineating the role of innervation in taste bud development is...
متن کاملTaste Bud-Derived BDNF Is Required to Maintain Normal Amounts of Innervation to Adult Taste Buds.
Gustatory neurons transmit chemical information from taste receptor cells, which reside in taste buds in the oral cavity, to the brain. As adult taste receptor cells are renewed at a constant rate, nerve fibers must reconnect with new taste receptor cells as they arise. Therefore, the maintenance of gustatory innervation to the taste bud is an active process. Understanding how this process is r...
