Electrode array apparatus, neurological condition detection apparatus, and method of using the same

A method for positioning electrodes, the method comprising:

• positioning headgear on a head of a patient so that electrodes attached to the headgear engage the head of the patient when the headgear is on the head of the patient, a first strip positioned on an outer top surface of the headgear that extends from a front of the headgear to a rear of the headgear, the first strip having a right lateral side extending between the front of the headgear and the rear of the headgear and a left lateral side extending between the front of the headgear and the rear of the headgear, a second strip attached to the front of the headgear or the rear of the headgear, the second strip having a first end positioned adjacent a right side of the headgear beyond the right lateral side of the centerline indicator and a second end positioned adjacent a left side of the headgear beyond the left lateral side of the centerline indicator, the second strip being a polygonal shaped strip extending linearly and horizontally from the first end of the second strip to the second end of the second strip in a direction that is perpendicular to a direction at which the first strip extends from the front of the headgear to the rear of the headgear, the second strip being spaced apart from a nose of the patient when the headgear is positioned on the head of the patient;
• and
• adjusting the headgear based on how the first strip and the second strip appear to adjust the headgear so that the first strip is centered on a top of the head of the patient while the second strip is spaced apart from the nose of the patient.
