We examined the biases in vection strength caused by motion direction (temporonasal vs. nasotemporal motion) and position of stimulus presentation (nasal and temporal semi-retinas) to investigate a subcortical contribution to vection. These biases have been identified for optokinetic nystagmus (OKN) and are acknowledged as evidence for a subcortical origin of OKN. In experiments, subjects monocularly observed hemi-field motion stimuli and made magnitude estimations. The results indicated… CONTINUE READING
