Extract:

An EEG-based brain-computer interface for cursor control describes a brain-computer interface system with control of the mu rhythm at the C3 position.

[edit] Method

  • Preliminary study on 60 normal subjects to identify best electrode position: C3 and C4. C3 was chosen as subjecs were right-handed.
  • Electrodes "placed 3 cm anterior and posterior to C3"
  • Computation of power around 9 Hz every 333 ms.
  • Square root of power ranges determined cursor movement

[edit] Subjects

Five subjects were included in the actual study. One of the subjects never learned to control his/her mu rhythm.
