Neuropeptides modulate rat chorda tympani responses.
The neuropeptide leptin has been shown to selectively modulate rat chorda tympani (CT) responses to sweet tastants. To explore whether other neuropeptides can modulate such responses, rat whole nerve CT responses to NaCl, HCl, quinine HCl, and sucrose were measured while administering cholecystokinin-8 (CCK-8), substance P(4-11) (SP(4-11)), or calcitonin gene-related peptide (CGRP). To avoid po...
متن کاملGustatory responses of the mouse chorda tympani nerve vary based on region of tongue stimulation.
Different parts of the mouth vary in their taste responsiveness and gustatory transduction components. However, there have been few attempts to consider regional variation among areas innervated by a single nerve branch or containing only one type of gustatory papilla. Here, we examined whether taste-elicited responses of a single nerve, the chorda tympani (CT), depend on where taste solutions ...
متن کاملEffect of nicotine on chorda tympani responses to salty and sour stimuli.
The effect of nicotine on the benzamil (Bz)-insensitive (transient receptor potential vanilloid-1 variant cation channel, TRPV1t) and the Bz-sensitive (epithelial Na(+) channel, ENaC) salt taste receptors and sour taste was investigated by monitoring intracellular Na(+) and H(+) activity (pH(i)) in polarized fungiform taste receptor cells (TRCs) and the chorda tympani (CT) nerve responses to Na...
متن کاملDevelopment of chorda tympani taste responses in rat.
To learn whether neurophysiological taste responses change during structural development of the gustatory system, we recorded from the chorda tympani nerve in rats aged 7 to 92 days after birth. Chemical stimuli applied to the anterior tongue included four monochloride salts, two acids, sucrose, and urea. Responses to all chemicals were obtained as early as 7 days postnatally. Developmental cha...
متن کامل[Chorda tympani neuroma].
This was a 45-year-old woman that initially consulted for a progressive hearing loss and dizziness of some 6 months of evolution. There were no notable relevant antecedents, while in the physical examination the otoscopy showed a greyish image that protruded in the posterior tympanic areas (Fig. 1a). The preoperative audiometry reflected a nixed right hearing loss with a mean loss in conversati...
