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 disclosed herein includes a cap to be worn on a head of a person and a first electrode carried by the cap. The first electrode holder defines a first opening therethrough. The example headset includes a first electrode that insertable into the first opening. The first electrode has a first length and is adjustable in the first opening to a first plurality of discrete positions having different depths of insertion relative to the first opening. The first electrode is to engage the head of the person when inserted a sufficient depth into the first opening. The example headset also includes a second electrode that is interchangeable with the first electrode and insertable into the first opening. The second electrode has a second length, greater than the first length, and is adjustable in the first opening to a second plurality of discrete positions having different depths of insertion relative to the first opening. The second electrode is to engage the head of the person when inserted a sufficient depth into the first opening.

主权项

1. A headset comprising:
a cap to be worn on a head of a person; a first electrode holder carried by the cap, the first electrode holder defining a first opening therethrough; a first electrode insertable into the first opening, the first electrode having a first length, a plurality of discrete annular rings extending around an outer surface of the first electrode, the first electrode rotatable in the first opening, the first electrode being adjustable in the first opening to a first plurality of different depths of insertion relative to the first opening, the first electrode to engage the head of the person when inserted a first depth into the first opening; and a second electrode interchangeable with the first electrode and insertable into the first opening, the second electrode having a second length greater than the first length and being adjustable in the first opening to a second plurality of different depths of insertion relative to the first opening, the second electrode to engage the head of the person when inserted a second depth into the first opening.
