Motion aftereffect by means of circular vection depicts role of MST and OP2 in visual-vestibular interaction

Aim: Several works have revealed a robust visual-vestibular interaction at the cortical level. Functional neuroimaging with conflicting visual or vestibular stimuli have repeatedly demonstrated a reciprocal inhibition as the mode of action (1). Our hypothesis was that the occurrence of this interplay may be confined to a general (ego-)motion detection network. The aim of this fMRI and videooculography (VOG) study was to induce egomotion whilst at the same time being able to differentiate the phenomenons of torsional afternystagmus and the motion aftereffect (MAE). Methods: Therefore, the differential effects of…
