Abstract: Provided herein are methods for EEG monitoring of a patient, which includes: positioning an array comprising a plurality of EEG electrodes on the patient's head; recording, during a first time period, a first data set of EEG signals from a first set of spatial scalp locations; manipulating the array to record, during a second time period, a second data set of EEG signals from a second set of spatial locations including at least some spatial scalp locations that are different from the first set of spatial scalp locations; integrating the first and second data sets, thereby generating a combined data set with a higher spatial density; and processing the combined data set to determine EEG events.

Abstract: A diagnostic system includes an array of electrodes, which are coupled to a body surface of a living subject at different, respective positions in proximity to a region of interest within the body. A switched impedance network applies varying loads to the electrodes. A processor is coupled to receive and measure electrical signals from the electrodes as a function of the varying loads, and to analyze the measured signals so as to compute a local electrical characteristic of one or more locations within the region of interest.

Abstract: A device is presented for use in an EEG measurement performed in the presence of a magnetic field. The device includes a wiring array for connecting an electrodes arrangement to an electroencephalogram (EEG) monitoring device. The wiring array includes sampling lines arranged to form first and second groups of sampling lines, arranged in a spaced-apart substantially parallel relationship extending along first and second axes respectively, at least some of the sampling lines being wire bundles including a plurality of wires for connecting to a corresponding plurality of electrodes of the EEG electrodes arrangement; the first and second groups of sampling lines intersect with each other to form a net structure when placed on area of measurement. The wiring array thereby enable generation of EEG data characterized by reduced motion artifact and/or reduced gradient artifact associated with the presence of the magnetic field during the EEG measurement.
