In collaboration with researchers at the Wadsworth Center and Dr. George Townsend , Algoma University, we are investigating a variety of different stimulus presentation paradigms. Our initial results show that manipulating the stimulus presentation sequence can significantly improve the speed and accuracy of the P300-BCI.
In collaboration with Dr. Leigh Hochberg and a team of researchers at the Massachusetts General Hospital, in addition to Theresa
Vaughan at the Wadsworth Center, we have been testing the P300-BCI with patients who
are in an acute care setting and have no means of verbal communication. To date, we
have had modest results in this setting; however, with recent protocol and software
modifications we are confident that the project will ultimately be successful. The
overall implications of a BCI in the acute care environment could reach well beyond
individuals with severe motor disabilities to provide enormous benefit and relief
to patients in an already undesirable situation.

Collaborators at Quantum Applied Sciences and Research, Inc. (QUASAR) have developed a novel "dry" electrode. Standard "wet" electrodes require a conductive
electrolyte solution to make contact between the electrode and the scalp. The QUASAR
electrode does not need conductive electrolyte. Each electrode has many small "fingers"
that can reach through the hair and make contact with the scalp. We have conducted
a recent study demonstrating that the dry electrodes can perform as well as standard
wet electrodes. These results are important in so much as they may allow the BCI end
user significantly more comfort leading to more BCI use, and less overall maintenance
of the system.

Over the past four years, while we were both at the Wadsworth Center, Dr. Dean Krusienski,
University of North Florida, and I collaborated with Dr. Dennis McFarland of the Wadsworth
Center and continue to investigate a number of signal processing techniques in an
effort to improve P300 BCI speed and accuracy. In addition, based on our finding,
Dr. Krusienski has developed a graphical user interface (GUI) that can be directly
imported into the BCI2000 software program (a BCI stimulus and recording program that
is used by approximately 300 research laboratories worldwide) to rapidly conduct online
experiments. Based on the success of our methods and the GUIs ease of use, it is now
packaged as part of the BCI2000 software release. BCI2000 is maintained by Dr. Gerwin Schalk at the Wadsworth Center and it is free for educational and research purposes.
