[Reactions of neurons of the vagal lobe of the carp medulla oblongata to stimulation of chemoreceptors of the skin surface, oral cavity and gills].
In the experiments on immobilized carps it was found that the units of the vagal lobe of medulla oblongata respond not only to the stimulation of the mouth cavity and gills, but of skin chemoreceptors as well. The units responding selectively to skin surface stimulation are less in number than those responding to stimulation of the two other receptive fields. There are significant differences between the changes in unit activity elicited by natural alimentary stimulus (extract from the food product) and by hydrochloric acid and sodium chloride. Comparison of neuronal responses to stimulation of skin chemoreceptors in vagal and facial lobes revealed a different role in processing afferent information from skin chemoreceptors.
