About us

The Psychophysiology and Optical Imaging working group focuses on measuring brain function and peripheral physiological variables (e.g. skin conductance) in psychiatric patients (e.g. schizophrenia, affective disorders, anxiety disorders, ADHD, dementia) and healthy control subjects.

Methods

The aim of the investigations is to record pathophysiologically relevant processes and to measure and predict changes in the context of therapeutic interventions. Both electrophysiological methods (electroencephalography, EEG; electromyography, EMG; evoked potentials, EP; measurement of electrodermal activity, EDA) and the technique of functional near-infrared spectroscopy (fNIRS), an optical method of functional imaging with which the oxygenation of brain tissue can be recorded non-invasively with good temporal resolution, are used.

In terms of content, the majority of current studies focus on the function of the frontal brain, with executive control functions such as inhibition, action control and monitoring as well as conflict processing taking center stage. We are also interested in investigating higher-level processes, including working memory, approach and avoidance behavior and emotion regulation. A further focus of the working group is the combination of different methods that serve the holistic understanding of the pathophysiology of psychiatric disorders and the mechanisms of action of corresponding therapeutic interventions.
