The Jamming Avoidance Response of High Frequency Electric Fish
Using a frequency difference (Δ F) clamp to maintain a stimulus and frustrate the normal escape from a jamming frequency, the response is found to be a characteristic function of the ΔF between stimulus and fish (Figs. 2, 3, 4, 6). It is graded on both sides of a best ΔF of about 3 Hz (= 0.3% in Sternarchus, 1.0% in Eigenmannia). There is no systematic response when F stimulus = F fish, regardless of phase.
