Cognitive Neurology

Research group „Cognitive Neurology”

Our main research focus is lesion studies in stroke patients with resulting anosognosia as well as with central-vestibular and cognitive impairments. By employing state-of-the-art lesion methods we showed that the right posterior insula is remarkably often affected in stroke patients with anosognosia. We could show recently, that the right posterior insular cortex plays an important role in motion perception as well as in body perception. Further, 92% of the patients suffering from asomatognosia/ somatoparaphrenia also had anosognosia for hemiparesis. This implies a behavioral and anatomical relationship between motion perception and body perception. Our results corroborate earlier studies and case descriptions and support the interoceptive model of the insular cortex and its impact on body- and motion perception. Within a BMBF funded research collaboration we could show that the tilt of the subjective visual vertical (SVV, a sign of vestibular otolith dysfunction) is associated with the insular cortex.
