Head-mounted electrode array
First Claim
1. A headset for detecting brain electrical activity of a human subject comprising:
- a substrate dimensioned to fit a forehead of the subject;
a plurality of electrodes disposed on the substrate so that the electrodes contact the subject when the headset is positioned on the subject;
wherein a first electrode is configured to contact a lower center region of the forehead, a second electrode is configured to contact an upper center region of the forehead, a third electrode is configured to contact a front right region of the forehead, a fourth electrode is configured to contact a front left region of the forehead, a fifth electrode is configured to contact a right side region of the forehead, and a sixth electrode is configured to contact a left side region of the forehead;
a nasion point, wherein the nasion point extends a consistent, predetermined distance from the first electrode and is dimensioned so that when the first electrode is aligned with the lower center region of the forehead, the nasion point is configured to be positioned between the eyebrows of the subject;
a base interface region configured to be substantially aligned with a nasal centerline of the subject, the base interface region configured to extend from the substrate toward a top region of the subject'"'"'s head; and
circuitry associated with the substrate and operably coupled to each of the plurality of electrodes.

Abstract
A headset for defecting brain electrical activity may include a flexible substrate having first and second ends each configured to engage an ear of a subject and dimensioned to fit across the forehead of a subject. The headset may also include a plurality of electrodes disposed on the substrate and configured to contact the subject when the headset is positioned on the subject. First and second electrodes may contact top center and lower center regions of the forehead, respectively, third and fourth electrodes may contact front right and front left regions of the forehead, respectively, fifth and sixth electrodes may contact right side and left side regions of the forehead, respectively, and electrodes included within the securing devices may contact the ear regions. The third and fourth electrodes may be moveable in at least a vertical direction relative to the other electrodes.
