Why Use A Mirror To Assess Visual Pursuit In Prolonged Disorders Of Consciousness? Evidence From Healthy Control Participants, Damian Cruse, Marco Fattizzo, Adrian M. Owen, Davinia Fernández-Espejo Jan 2017

Why Use A Mirror To Assess Visual Pursuit In Prolonged Disorders Of Consciousness? Evidence From Healthy Control Participants, Damian Cruse, Marco Fattizzo, Adrian M. Owen, Davinia Fernández-Espejo

Background: Evidence of reliable smooth visual pursuit is crucial for both diagnosis and prognosis in prolonged disorders of consciousness (PDOC). However, a mirror is more likely than an object to elicit evidence of smooth pursuit. Our objective was to identify the physiological and/or cognitive mechanism underlying the mirror benefit. Methods: We recorded eye-movements while healthy participants simultaneously completed a visual pursuit task and a cognitively demanding two-back task. We manipulated the stimulus to be pursued (two levels: mirror, ball) and the simultaneous cognitive load (pursuit only, pursuit plus two-back task) within subjects. Results: Pursuit of the reflected-own-face in the mirror …
