Audiospatial evoked potentials for the assessment of spatial attention deficits in patients with severe cerebrovascular accidents

Introduction Neuropsychological assessment of spatial orientation in post-acute patients with large brain lesions is often limited due to additional cognitive disorders like aphasia, apraxia, or reduced responsiveness.Methods To cope with these limitations, we developed a paradigm using passive audiospatial event-related potentials (pAERPs): Participants were requested to merely listen over headphones to horizontally moving tones followed by a...
