Electroencephalography electrodes are attached to the surface of the scalp at predetermined points and are connected to relatively long lead wires which are anchored to the patient's skin at a short distance from the electrode itself to provide a strain relief on the lead wire and to minimize signal interference or artifacts associated with movement of the lead wire and the electrode. The arrangement provides for placing a preamplifier unit in a position on the patient's body which is more comfortable and less cumbersome than if mounted directly adjacent the electrodes themselves. The electrode and lead assembly may be provided with a thickened portion of the lead insulation to increase the surface area available for anchoring the lead by tape or other adhesive.
