A number of measuring electrodes for emplacement on the head of a patient, signal amplifiers whose input channels are connectable, via a selector, to the measuring electrodes according to a pattern selection program, and recorders controlled by the output signals of the signal amplifiers. The selector manifests, in a head-image area, one electrode switch for each measuring electrode, by means of which electrode switch the measuring electrode is connectable to an input channel, and which electrode switch is arranged in a position relative to the head-image area corresponding to the application location of the measuring electrode.
