Neural responses from visual stimuli known to provoke motion sickness: a near infrared spectroscopy study – Hong Kong Research Grant Council

In 2005, the International Workshop Agreement 3 (IWA3, 2005) concluded that more research on the etiology of visually induced motion sickness (VIMS) is needed. Several hypothetical neural pathways for the development of VIMS have been presented but remained untested. The proposed study will use near infrared spectroscopy (NIRS) to measure changes in levels of oxyhaemoglobin associated with visual stimuli that are known to produce various levels of motion sickness. In particular, the study will search for repeatable patterns of NIRS responses related to the presence and absence of vection sensation.

Part of the research will take place at the motion simulator located at the CLP Power Wind/Wave Tunnel Facility (WWTF) at HKUST. This motion platform can generate low frequency movements that can provoke motion sickness. The PI of the project is Professor Richard So who is a leading expert in motion sickness and ergonomics. He is the Fellow of the Institute of Ergonomics and Human Factors and Member of Commission Internationale de L'eclairage (CIE) Technical Committee TC1-67.
