 Abstract: Introduction: The sensation of motion is a product of the integration of information from multiple sensory modalities; vestibular, visual and proprioceptive information all have strong influences on the perception of self-motion. Here we present an electroencephalogram (EEG) study which demonstrates a P3 response to a self-motion oddball paradigm. Methods: Subjects were placed in a Maxcue Stewart motion platform. Auditory and visual cues were minimised using white noise and an enclosed environment. They were translated linearly 7cm using a 1s long sinusoidal acceleration profile at a 45° angle forwards and left or right, with a probability of 0.8 / 0.2, balanced over runs (oddball paradigm). Subjects responded to the infrequent direction by pressing a button. During the task, EEG data were recorded using a Biosemi ActiveTwo 128-channel EEG system. The recordings were processed offline to remove artifacts. Results / Conclusion: Statistical parametric mapping shows the frequent and infrequent event-related potentials (ERPs) to differ significantly from 500ms - 950ms. Topographic analysis shows a typical P3 topography. Response-epoched ERPs show a peak of width approx 300ms. Conclusion: These results indicate that a P3-like response is generated by the motion oddball paradigm.
