Time course of morphological alterations of fungiform papillae and taste buds following chorda tympani transection in neonatal rats.
The time course of structural changes in fungiform papillae was analyzed in rats that received unilateral chorda tympani nerve transection at 10 days of age. Morphological differences between intact and denervated sides of the tongue were first observed at 8 days postsection, with an increase in the number of fungiform papillae that did not have a pore. In addition, the first papilla with a fil...
متن کاملNeuron/target matching between chorda tympani neurons and taste buds during postnatal rat development.
During postnatal development, a relationship is established between the size of individual taste buds and number of innervating neurons. To determine whether rearrangement of neurons that innervate taste buds establishes this relationship, we labeled single taste buds at postnatal day 10 (P10) and again at either P15, P20, or P40 with retrograde fluorescent neuronal tracers. The number of singl...
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 کاملObservation of regenerated fungiform taste buds after severing the chorda tympani nerve using confocal laser scanning microscopy in vivo.
OBJECTIVE To evaluate whether regenerated fungiform taste buds after severing the chorda tympani nerve can be detected by confocal laser scanning microscopy in vivo. STUDY DESIGN Retrospective study. SETTING University hospital. PATIENTS Six patients with a normal gustatory function (Group 1), 9 patients with taste function recovery after severing the CTN (Group 2), and 5 patients without...
متن کاملFungiform taste bud degeneration in C57BL/6J mice following chorda-lingual nerve transection.
Taste buds are dependent on innervation for normal morphology and function. Fungiform taste bud degeneration after chorda tympani nerve injury has been well documented in rats, hamsters, and gerbils. The current study examines fungiform taste bud distribution and structure in adult C57BL/6J mice from both intact taste systems and after unilateral chorda-lingual nerve transection. Fungiform tast...
