1. An electrode array for detecting brain electrical activity of a human subject comprising:
a substrate dimensioned to fit a forehead of the human subject;
a plurality of electrodes coupled to the substrate so that the plurality of electrodes contact the subject when the electrode array is positioned on the human 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, and a fourth electrode is configured to contact a front left region of the forehead,
wherein the third electrode is coupled to the substrate via a first connector extending vertically downward from the substrate, and
wherein the fourth electrode is coupled to the substrate via a second connector extending vertically downward from the substrate; and
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 human subject.
