Method and apparatus for conducting brain function diagnostic test
First Claim
1. Apparatus for use in conjunction with an electroencephalographic (EEG) test, said apparatus comprising:
- a headset comprising a rigid helmet liner having an interior portion which is adapted to be accommodate the head of a subject to be EEG tested, said headset including a plurality of apertures provided at predetermined locations about said headset;
a plurality of electrodes, each of said electrodes being resiliently suspended in at least one of the apertures provided in said headset by the use of a resilient material provided within said aperture and secured to both the electrode and the headset; and
means for displacing the electrodes in a direction toward the interior of said headset and means for holding the displaced electrodes in a fixed, displaced position so as to provide constant physical and electrical contact with the head of the subject in order that reliable EEG measurements may be taken.

Abstract
Method and apparatus are provided for use in conducting an electroencephalographic (EEG) test where the apparatus includes a headset suitable for placement on the head of a subject to be tested. A plurality of electrodes are mounted on the headset at pre-determined positions about the headset. The electrodes are preferably mounted to the headset by the use of a resilient material, preferably a resilient wire or plastic mesh which is bonded to both the electrode assembly and to the headset.
Each of the electrode assemblies include a separate air cylinder for displacing the electrode in the direction of the subject'"'"'s head upon the application of additional air pressure into the cylinder. A bellows arrangement is provided within each air cylinder for effecting displacement of the electrode.
Means are further provided for dispensing a predetermined amount of an electrolytic material from an external source of electrolyte, through the electrode, to the point of contact between the electrode and the subject'"'"'s head.
