Eye and head movements to auditory targets.

Three adult female monkeys were trained to direct their gaze toward auditory targets. When the animals were free to move their heads about the vertical axis, this was accomplished with short-latency, coordinated eye-head movements reminiscent of responses to visual targets. The similarity of response to auditory and visual targets suggests a common motor program elicited by stimuli of different modalities. Since these modalities do not share the same reference system, this implies a remapping between the two reference systems.
