Onset dynamics of pattern recognition and steering analyzed with a split-song paradigm. (A) The velocity of lateral steering increased with the beginning of the split-song and revealed steering movements toward the left and right side. The path of the cricket deviated slightly to the left, the side from which the first pulse of each chirp was presented. (B) The onset dynamics of pattern recognition and steering was revealed by averaging the response (n = 60) to the first four chirps. Crickets steered toward the first pulse of the first chirp (asterisk). (C Upper) The histogram reveals that steering increased during the first seven pulses presented. (Lower) The average lateral steering velocity for selected chirps of the sound pattern. The response increased from the first to the fourth chirp and then remained constant. Error bars indicate the SEM.
