[Electrical response of frog lingual epithelium to stimulation of the gustatory nerve]. 1983

A L Byzov, and A I Esakov, and M S Bukhtiiarov

Electrical stimulation of the gustatory nerve evoked a positive electrical response of the outer surface of the tongue (relative to its inner layers). The amplitude and the rate of rise of the response grew and the latency fell with increased frequency of stimulation. The response originated in the superficial epithelial layer (30-60 micrometers) and was produced by a decrease of "resting potential" (negative-outside) of this layer. The response was accompanied by a strong decrease of the superficial tongue layer resistance and arose probably as a result of short-circuiting of the epithelial layer by high-conductive nonspecific channels. Similar response accompanied by a decrease of the superficial tongue layer resistance was recorded with adequate stimulation (by acetic acid vapours). The results are compared with the response of the frog skin to the stimulation of cutaneous nerve.

UI	MeSH Term	Description	Entries
D010525	Peripheral Nerves	The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.
