Responses of single units to sinusoidal homogenous electrical and magnetic field stimulation were studied in the lateral-line lobes of the skate Raja radiata. The voltage gradient thresholds were in the range of 0.03-10 microV/cm. Optimal frequency ranges for electrical and magnetic stimuli were 0.05-0.5 and 2-3 Hz, respectively. Possible mechanisms and(More)
The impulse activity of nerve fibres in response to electric pulses and sinusoidal electric current stimulation of the electroreceptors was recorded in Lampetra fluviatilis. The electroreceptors of lamprey were excited by cathodal stimuli. Thresholds for electric stimulation were in the range of 10-60 microV/cm. Optimum frequency range in uniform electric(More)
A large portion of the central nervous system of the skate Raja radiata was examined for responses related to single electroreceptor organs (ampullae of Lorenzini) or their groups. It was shown that electroreceptors project to the anterior lateral lobes of the medulla, caudal portion of the auricles and the mesencephalon. A topographic segregation of(More)
Experiments with recording of single fibre impulse activity from lateral-line nerve in Turkestan catfish (Glyptosternum reticulatum) show that the fish has a high-sensitive electroreceptor apparatus (threshold value in a uniform electric field was 1 muV/cm). The effective stimulus for the electroreceptors is the voltage drop across the fish skin. Impulse(More)
