BCI technology can offer individuals with severe motor disabilities greater independence and a higher quality of life. The BCI systems take recorded brain signals and translate them into real-time actions, for improved communication, movement, or percep­ tion. Four patient participants with a clinical need for intracranial electrocorticography (ECoG) participated in this study. The participants were trained over mul­ tiple sessions to use motor and/or auditory imagery to modulate their brain signals in order to control the movement of a computer cursor. Participants with elec­ trodes over motor and/or sensory areas were able to achieve cursor control over two to seven days of train­ ing. These findings indicate that sensory and other brain areas not previously considered ideal for ECoG-based control can provide additional channels of control that may be useful for a motor BCI.
