Abstract: An electrode arrangement measures electric voltages and currents in the human body and provides electro-simulation of the human body. The electrode arrangement contains an electrode array with a flexible support. A number of electrodes are arranged in a grid on the same side of the support and slots are disposed between the individual electrodes starting from the outer edge of the support. An elastic intermediate layer that has one recess for each electrode is provided, each recess defining a cavity to be filled with an electrically conductive gel.

Abstract: A training and simulation assembly for the learning of deliberate control of a specified body part by a test subject contains an electrode cap, which has a number of electrodes, and an evaluation unit, which is configured to measure voltages present at the electrodes and to provide measurement results as EEG measurement data. The evaluation unit analyzes the EEG measurement data for the presence of a mental act and to determine a correspondence value, which indicates the correspondence of the EEG measurement data with reference values defined by the mental act. A control unit and a simulation unit are provided. The simulation unit stimulates the body of the test subject at a specified point of the body and/or to trigger a motion. The control unit controls the stimulation unit and the ability to apply an indicating stimulus to the body part by the stimulation unit.

Abstract: The perceptive faculties of a subject are determined by way of a brain-computer interface 20. At least two mutually distinguishable types of stimuli SA, SB which are applicable to a subject are prescribed. A multiplicity of temporally successive stimuli are applied to the subject and combined to form blocks. Calibration data are created from the EEG data ascertained thus by virtue of a number of ascertained EEG data and stimuli associated with these EEG data are combined to form calibration blocks. A classification function is ascertained by a classification analysis on the basis of ascertained calibration blocks. The classification function specifies a position of the stimulus of the first type in the respective calibration block. Finally, the EEG data of a number of test blocks selected from the blocks are subjected to the classification function.

Abstract: A method and an apparatus provide electro stimulation to a test subject. A number of electrodes are connected to the brain of a test subject, wherein the voltages present on the individual electrodes are measured and analyzed after the delivery of a stimulus. During a preselection based on the analysis, individual electrodes are selected for the delivery of a stimulus, wherein one electrode is selected from the individual preselected electrodes and the stimulus is delivered to the brain by the electrode. Accordingly, in the analysis using the measurement signals during the preselection, the signals present on the electrodes are examined, in particular exclusively examined, for the presence of signal power or signal energies in the range from 60 Hz to 1 kHz, in particular between 60 Hz and 180 Hz.

Abstract: An electrode cap contains at least one electrode array and is to be applied to a subject's head. The electrode array contains an insulating layer, two electrodes disposed opposite one another on the insulating layer, namely a first measurement electrode facing toward the subject's head and a reference electrode facing away from the subject's head. A conductive body abuts the reference electrode and is in electrical contact therewith, and is arranged on the side of the reference electrode that faces away from the subject's head. The individual conductive bodies of all the electrode arrays are electrically connected to each other.

Abstract: Differently perceptible types of stimuli are applied to the a test subject and the test subject is set intellectual tasks which, in the presence of a stimulus, are intended to be performed according to the nature of this stimulus. In a plurality of test steps a particular type of stimulus is chosen from the set of possible types of stimuli and applied to the person. During or after the application of the respective stimulus, EEG data of the person are determined and recorded preferably within 1 to 10 seconds. Classification analysis is used to determine a measure of whether the EEG data assigned to a defined stimulus are distinguishable from the EEG data assigned to a stimulus of a different type. The measure of the distinguishability of the EEG data of different stimuli is used as a measure of the perceptive faculty.
