The group investigates the neural mechanisms underlying perception and evaluation of visual information in healthy subjects and in patients with lesions that lead to learning disturbances. We are equally interested in basic science as well as in clinical-pathological aspects. The basic science aspect concerns processes related to visual attention in dependence of different expectations or reward. For this topic we have a strong collaboration with the research group “Visual attention and perceptual learning”. Clinical-pathological aspects concern neuroplastic processes following one-time lesions like in stroke, as well as consecutively reoccurring lesions such as in neurodegenerative diseases (Parkinson’s disease, ALS). We employ non-invasive neuroimaging techniques (structural MRI, diffusion-weighted MRI and fiber-tracking, functional MRI in combination with high temporal resolution methods such as EEG and MEG) but also invasive recordings of neural activity in cooperation with the functional stereotactic neurosurgery group.
