Multimodal mapping of spatial attention for unilateral spatial neglect in VR: a proof of concept study using eye-tracking and mobile EEG

Unilateral spatial neglect (USN) is a complex spatial attentional disorder consisting of a failure to attend to the contralesional side of space, frequently seen after a stroke. However, the majority of cases go undiagnosed due to the lack of a valid and reliable tool that is able to assess USN and...
