  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.   Fungiform papillae density was measured in thirteen individuals (M = 6, F = 7) with a mean of 88 and range of 44– papillae/cm 2. Inspection for .

After neonatal chorda tympani (CT) transection, adult rats demonstrated a marked preference for a normally avoided salt, NH 4 Cl. In the present study, taste responses were recorded from the nucleus of the solitary tract (NST) in similarly CT-denervated rats to investigate a physiological basis for this behavioral phenomenon. Disappearance of fungiform papillae and taste pores in rats with unilateral chorda tympani section at 10 days postnatalChemical Senses21, Google Scholar Spitzer, A.

A second possibility is that some gustatory NTS units receive input directly from capsaicin-sensitive chorda tympani fibers (Okuni, ), although other studies indicate that chorda tympani fibers are not capsaicin sensitive (Silver et al., ; Hiura et al., ). The organ in the frog’s palate, so-called “Sinneshügel” (Bethe, ), is distributed at a rate of 3–5/mm 2, and the estimated total number over the entire palate is about (Suzuki, ), which is approximately similar to the number of fungiform papillae in the tongue (Kusano and .

Fibers of the chorda tympani nerve typically innervate taste cells in multiple fungiform papillae, although the sensitivities of each branch appear to be highly similar, suggesting that taste axons are guided to make connections to particular.

In mammals the sensory fibers for taste travel in three mixed nerve trunks: the lingual, the glossopharyngeal, and the vagus. The Ungual nerve, more specifically its branch the chorda tympani innervates taste buds of fungiform papillae of the anterior portion of the tongue.

Single rat fungiform papillae are innervated by 3–14 GG neurons (Krimm and Hill ), and single hamster taste buds are innervated by an average of 15 GG neurons (Whitehead et al.

Thus GG/CT receptive fields are innervated by more than one ganglion cell, further contributing to the complexity of the afferent input. The former innervates mostly fungiform papillae in the anterior two-thirds of the tongue, while the latter innervates circumvallate and foliate papillae in the posterior one-third of the tongue.

Peripheral interactions among single papilla inputs to gustatory nerve fibers, J. Gen. Physiol. PubMed M., and Yamashita, S., Single fibers of the bullfrog glossopharyngeal nerve give rise to several peripheral branches, each innervating separate fungiform papillae on the dorsal surface of the tongue.

Extracellular electrodes were used to stimulate and record simultaneously from several papillae and from the central branch. Minor changes in centrally recorded neural output were caused by collision of action. Transection of the chorda tympani nerve (CTX) in the adult rat results in an initial degeneration or loss of taste buds that are contained within fungiform papillae (Hård af Segerstad et al., ).

Upon regeneration of the chorda tympani nerve (CT), taste buds. The chorda tympani branch (CT) of cranial nerve VII innervates the taste buds of the anterior two-thirds of the tongue. These taste buds are housed in specialized protrusions on the lingual surface called fungiform papillae. In the rat, each papilla usually houses a single taste bud (Miller and Preslar, ).

The lingual—tonsilar branch of. the left lingual and the right chorda tympani. Thus, the design of the experiment eliminated all of the tongue taste input save that provided by the cross-regenerated IXth nerve (IXe-Cp) in the experimental groups, and either a single IXth or single chorda tympani nerve in the 2 control.Introduction.

The chorda tympani (CT) nerve innervating the anterior part of the tongue contains two types of NaCl-responsive fibers. One, the N-type, receives input from receptor cells and the NaCl responses are strongly inhibited by amiloride, a blocker of the epithelial sodium channel (ENaC).DeSimone JA and Ferrell MF () Analysis of amiloride inhibition of chorda tympani taste response of rat to NaCl.
