[Rhythmic activity of the olfactory bulb of the carp under nembutal anesthesia]

The effect of nembutal intraperitoneal injections upon the induced waves and orthodromic potentials of the olfactory bulb (OB) induced by odor stimulation and paired electric stimuli of the olfactory nerve was examined in immobilized by diplacine carp (cyprinus carpio L.). The nembutal anesthesia resulted in a gradual decrease in frequency of induced waves tested by orthodromic response and amplitude of spontaneous electric activity ob OB. The changes found under nembutal anesthesia in evoked electric activity of OB were also observed in chronic and acute intersection of the olfactory tracts.
