[Neuronal activity of the frog medulla oblongata in response to chemical stimulation of gustatory and cutaneous chemoreceptors]. 1981

L T Zharova, and N P Kurzina

The unit activity of medulla oblongata extracellularly recorded during stimulation of the taste receptors and skin chemoreceptors with solutions of the hydrochloric and citric acids, sodium chloride and potassium chloride, in the majority of neurons responded at least to the solutions of one acid and one salt. The number of units which responded to all the solutions was twice as high on stimulation of taste receptors than skin chemoreceptors. The chemical stimuli graduation analysis is more suitable in the case of taste receptor stimulation. The peculiarities of the primary center unit activity response to the stimulation of the receptive fields in question may be connected with different role of taste and skin chemoreceptors in adaptive behaviour.

D008526	Medulla Oblongata	The lower portion of the BRAIN STEM. It is inferior to the PONS and anterior to the CEREBELLUM. Medulla oblongata serves as a relay station between the brain and the spinal cord, and contains centers for regulating respiratory, vasomotor, cardiac, and reflex activities.

D002628	Chemoreceptor Cells	Cells specialized to detect chemical substances and relay that information centrally in the nervous system. Chemoreceptor cells may monitor external stimuli, as in TASTE and OLFACTION, or internal stimuli, such as the concentrations of OXYGEN and CARBON DIOXIDE in the blood.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012867	Skin	The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
D013650	Taste Buds	Small sensory organs which contain gustatory receptor cells, basal cells, and supporting cells. Taste buds in humans are found in the epithelia of the tongue, palate, and pharynx. They are innervated by the CHORDA TYMPANI NERVE (a branch of the facial nerve) and the GLOSSOPHARYNGEAL NERVE.	Bud, Taste,Buds, Taste,Taste Bud
