Abstract: Sensor means for detection of bioelectrical signals, in particular, for implantation into or onto a brain wherein the sensor means comprises a first number of electrodes which can be coupled to a biological organism, in particular, to neural cells of a nervous system for tapping a first plurality of electrical potentials at the biological organism. According to the invention, the sensor means comprises means for providing an averaged electrical reference potential. The averaged electrical reference potential is formed from a plurality of detected electrical potential that are tapped at the biological organism.

Abstract: The invention relates to a probe for data transmission between a brain and a data processing device. Said probe has a support with electrodes fitted thereto. Said electrodes can be made to electromagnetically interact with neurons of the brain for the purpose of detecting neuronal activity and/or the transmission of stimuli and can be coupled to the data processing device. The shape of the support can be adapted to an inner surface of the brain to such a degree that it can be inserted into the interior of a sulcus of the brain.
