Functional brain activity in persistent postural-perceptual dizziness (PPPD) during galvanic vestibular stimulation reveals sensitization in the multisensory vestibular cortical network

Abstract Persistent postural-perceptual dizziness (PPPD) is often preceded by vestibular disorders. We applied galvanic vestibular stimulation (GVS) and related stimulus-evoked activity to individual ratings of perceived motion for each stimulus and to perceived egomotion thresholds by GVS and behav...
