An apparatus for sensing electrical currents in a subject has a geodesic net structure of electrode elements connect by flexible legs. The electrode elements each have an inner electrode facing and sensing electrical currents in the subject and an outer layer electrode facing away and sensing external electrical noise. The legs have flexible conductive material that electrically connects the outer electrodes so that they are all connected and are electrically the same or similar to the subject's body part. The outputs of the electrodes are converted to multiplexed digital signals and transmitted to signal processing circuitry that identifies the noise present in the signals from the outer electrodes and removes the noise from the signals from the inner electrodes so as to output clean EEG data for each inner electrode. Additional electrodes that detect extraneous neuro-muscular currents are also used to determine the noise in the inner electrode output signals.
