Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Studies of gaze control in labyrinthine-deficient (LD) patients have revealed a variety of adaptive mechanisms that may be used to compensate for loss of the vestibuloocular reflex (VOR), including central preprogramming of eye movements and the potentiation of the pursuit, optokinetic, and cervicoocular reflexes. To investigate the mechanisms that compensate for loss of the VOR during head-free pursuit we examined the responses to pursuit of pseudorandom target motion in LD patients under head-free and head-fixed conditions, using a stimulus that covers the frequency range of normal head-free pursuit movements.
