Methods and apparatus to gather and analyze electroencephalographic data

摘要

Example headsets and methods for gathering electroencephalographic signals are disclosed herein. An example headset includes an adjustment assembly including a first support to be disposed on a first side of a head of a person and a second support to be disposed on a second side of the head of the person. The example headset also includes an adjustor operatively coupled to the first support. Further, the example headset includes an electrode strip and a tension strap having a first end operatively coupled to the adjustor and a second end operatively coupled to the second support.

主权项

1. A headset comprising:
a first support to be disposed on a first side of a head of a person; a second support to be disposed on a second side of the head of the person opposite the first side; a first adjustor operatively coupled to the first support; a first electrode strip to be disposed over the head of the person such that a first end of the first electrode strip is disposed adjacent the first support and a second end of the first electrode strip is disposed adjacent the second support; and a first tension strap extending along and slidably coupled to the first electrode strip, a first end of the first tension strap operatively coupled to the first adjustor and a second end of the first tension strap operatively coupled to the second support, the first adjustor including a wheel rotatably coupled to the first support, the first tension strap to be wound about the wheel when the wheel is rotated to change a tension of the first tension strap.
