Systems and methods to gather and analyze electroencephalographic data
Example devices are disclosed herein that include a first elongated band coupled to a first housing to be located on a first side of a head of a subject and a second housing to be located near a second side of the head of the subject, the first elongated band comprising a first set of electrodes. The example device also includes a second elongated band coupled to the first housing and to the second housing, the second elongated band comprising a second set of electrodes. In addition, the device includes a third elongated band coupled to the first housing and to the second housing, the third elongated band comprising a third set of electrodes.
1. A headset comprising:
a first housing on a first side of the headset;
a second housing on a second side of the headset opposite the first side;
a first band to be disposed over a head of a subject, the first band including a first plurality of electrodes;
a first strap slidably disposed along the first band, the first strap coupled to the first and second housings;
a second band to be disposed over the head of the subject, the second band including a second plurality of electrodes; and
a second strap slidably disposed along the second band, the second strap coupled to the first and second housings, wherein the first band and the second band are independently repositionable relative to each other, wherein the first strap is adjustable to change a first position of the first plurality of electrodes relative to the head of the subject, and wherein the second strap is adjustable to change a second position of the second plurality of electrodes relative to the head of the subject, the first strap and the second strap being independently adjustable.
