[Activity of central neurons of the electroreceptor system of Glyptosternum reticulatum].

Acute experiments with extracellular recording of pulse activity from neurons of lateral lobes of the Turkestan catfish Glyptosternum reticulatum revealed tonic and phasic neurons. Tonic neurons as compared to phasic ones were more sensitive to a potential gradient in water and has spontaneous activity. Phasic neurons had no spontaneous activity, their responses did not depend on the intensity and duration of electric stimuli. The functional significance of the phasic neurons remains so far unclear.
