A method and arrangement for acquiring an electroencephalogram (EEG) are disclosed. A first set of electrodes is arranged to sense cortical signals generated primarily in a region of interest (ROI). A second set of electrodes are arranged to sense cortical signals generated inside and outside of the ROI. Individual signals sensed by each electrode of the first and second sets of electrodes are directed to a signal analyzer.

Device and method for carrying out spatially directed detection of an electroencephalogram

According to the invention, the eye of the subject is lit with light from the non-visible spectrum (infrared light) in such a way that its image, taken with an infrared camera, is of sufficiently high-contrast for an evaluation, so that the actual line of sight can be calculated from the picture based on the characteristics of the eye and that, proceeding from the determined line of sight, the coordinates of the coming optical stimulation can be adjusted in such a way that the intended retinal area is stimulated.
