Claim:
1. A measurement device for use in an electroencephalogram (EEG) measurement performed in the presence of a magnetic field, the measurement device comprising a wiring array for connecting an electrodes arrangement comprising a plurality of EEG electrodes to an EEG monitor comprising a control unit being configured and operable to analyze neural signals received from said electrodes arrangement and generate EEG data, wherein: the wiring array comprises a plurality of sampling lines arranged to form a first group of sampling lines arranged in a spaced-apart substantially parallel relationship extending along a first axis, at least some of said first group of sampling lines being a first group of wire bundles each comprising a plurality of first wires for connecting to a corresponding first plurality of electrodes, of said electrodes arrangement, extending along said first axis; and a second group of sampling lines arranged in a spaced-apart substantially parallel relationship extending along a second axis, at least some of said second group of sampling lines being a second group of wire bundles each comprising a plurality of second wires for connecting to a corresponding second plurality of electrodes, of said electrodes arrangement, extending along said second axis; wherein said first group of wire bundles intersects with said second group of wire bundles over an area of measurement locations when said wiring array is placed on a patient's scalp, the wiring array being configured and operable for simultaneously transmitting to the EEG monitor, first and second sets of EEG measurements obtained by electrodes of said electrodes arrangement being located in said area of measurement locations when said wiring array is placed on the patient's scalp, the first set being obtained along at least one sampling line of said first group of sampling lines and the second set being obtained across at least two different sampling lines of said second group of sampling lines, thereby enabling generation of EEG data characterized by at least one of a reduced motion artifact and a reduced gradient artifact associated with the presence of the magnetic field during the EEG measurement.
