Fig. 3. Field potentials recorded with bath electrodes during predatory strikes. The onset of the predator's muscle potential is indicated with an arrowhead in all traces. (A) An electrical recording of potentials produced during a medial giant neuron mediated escape tail-flip. The large and phasic motor giant (MoG) neuron potential is followed by fast flexor (FF) muscle potentials. (B) Muscle potential recorded during a lateral giant mediated escape tail-flip. A smaller phasic MoG neuron potential is visible, followed by FF muscle potentials. (C) Muscle potential recorded during a non-giant mediated tail-flip. The signal consists of small FF muscle potentials only, and no large and phasic potential can be seen.
