Brain Machine Interface
The Brain Machine Interface (BMI) work group focuses on neurophysiological approaches to decode intended movements or other actions from human brain activity (in particular as reflected in the electroencephalogram (EEG).
Patients after stroke or paraplegia often suffer from motor or sensory dysfunction. The goal of the BMI projects is to support these patients in regaining basic motor or sensory function by means of brain controlled devices.
Besides the EEG our research includes experiments based on brain magnetic fields (magnetoencephalogram (MEG) and functional magnetic resonance imaging (fMRI). The analysis of these signals is widely based on machine learning approaches.
Hermann Hinrichs studied physics at the University of Hanover from 1966 to 1972. There he received his doctorate in 1982 at the Institute for Theoretical Communications Engineering and Information Processing. In 1991 he acquired the venia legendi for Experimental Neurophysiology at the Hannover Medical School. In 1998 he was appointed an extraordinary professor. In addition to his work at LIN, he is responsible for research-related technology and methodology at the Department of Neurology of the OVGU. He is also a member of the board of directors of the research campus STIMULATE. His scientific interest is in the measurement and analysis of neurophysiological signals.

Brain-Machine Interface – OP planning and selection procedures (as subproject of the research campus STIMULATE)
The project is concerned with the investigation of paradigms and algorithms that make it possible to identify brain function for robust BMI control in different forms of brain lesion after stroke. On the one hand, this includes the individual optimal localization of non-invasive or invasive electrodes (grids) and, on the other hand, enables the detection of intended actions in the single triangle, i.e. in real-time, and the generation of machine commands. Therefore, in this work package, selection procedures are to be developed which allow a simple intuitive control of an autonomously acting robot arm.
In-Ear-BMI (as subproject of the research campus STIMULATE)
This project comprises the development and implementation of hardware and software components for a miniaturized system for the acquisition of EEG signals from the auditory canal, realized as a smartphone extension. Research goals include the development of suitable electrodes and electrode localizations, dedicated miniaturized amplifiers/signal converters and smartphone-based analysis software that can extract specific brain function parameters from the EEG based on neuroscientific approaches.
