Short-latency component of pinna movements during sensory probe trials. Acoustic broadband (800 msec, broadband noise) probes were presented in random trials from speakers located at (±90°,0°), (±63°,0°), (±45°,0°), (±18°,0°), (±9°,0°), and (0°,0°) while the cat fixated an LED at (0°,0°). The end of the movement traces coincided with the delivery of the reward 200 msec after stimulus offset. Notice in the conditions with the largest movements that the pinna returns to the initial position shortly after stimulus offset. For both left and right pinnae the trials corresponding to contralateral speaker positions at ±90°, ±63°, and ±45° were recorded in a different session than the rest of the data.
