Sound evoked head and jacket orienting responses. The upper panels show the orienting movements of a ferret performing a free-field sound localization task recorded from an infrared camera (60 frames s−1) using a reflective strip attached to the animal's head. The lower panel shows how the horizontal angle of the animal's head (red circles; mean + s.d.; n = 1110 trials) and jacket (blue circles; mean + s.d.; n = 932 trials) changed after a stimulus was presented from the +90° speaker position.
