TP Lehnen/Wachtler: Perception in Bodily Distress Disorders
PhD student Lena Schröder:
“Patients with Bodily Distress Disorder suffer from physical symptoms that cannot be sufficiently explained by organic dysfunction. Until today, little is known about the underlying mechanisms that cause these, so called functional, symptoms. However, recent efforts understand functional symptoms as a result of erroneous sensory processing, that establishes in early perceptual stages in the central nervous system.
Within my PhD, I aim to acquire a better understanding of the perceptual processes in Bodily Distress on the example of patients with functional dizziness. For this, we first plan to study the interplay between bottom-up sensory input and top-down expectations in a head motor control task using different behavioral measurements like eye and head movement recordings as well as computational modelling. Further projects will address perception outside of the deficient vestibular modularity, for example in time perception, as well as perceptual metacognition.”
