1. A conceptual model for the adaptation of perceived auditory space to changes in eye position.
A conceptual model for the adaptation of perceived auditory space to changes in eye position. Our findings are consistent with a physiological set-point adapter that defines the straight-ahead based on the position of the eyes in the orbit over time. The saccade and pursuit systems synergistically form a motor command to maintain eccentric eye position. The OMI converts a velocity signal into an imperfect control signal for eye position in the head. This position signal serves as an input to the set-point adapter (with a long time constant), which over time shifts auditory space, and possibly other sensory or motor maps at different rates, to approach the new perceived straight-ahead defined by eye position. In the clinical condition of rebound nystagmus, the output of the set-point adapter would reduce ocular drift and stabilize gaze over time.
