Abstract:
Recent work combining techniques from engineering, neuroscience, and neuropsychology have merged into an exciting new research field known as Brain Computer Interfaces.
This interface exists between the recording and subsequent interpretation of biological signals whereby the information is used to control an external device. In large
part, these new devices act as neuroprosthetics that aim at restoring damaged hearing, sight, and movement in pathological populations. Faculty from The University of
Mississippi have begun an initiative to design and fabricate both software programs to record brain activity (EEG) as well as hardware that may be used to help augment
any of the following: injury rehabilitation, language acquisition, and neurofeedback training. This lecture will address many of the common signal processing techniques
used to record evoked brain potentials, limitation associated with different measures, and the lay of the land for future BCI endeavors.
Dwight Waddell is an assistant professor in the Department of Health, Exercise Science and Recreation Management at the University of Mississippi. He is currently the
director of the Cognitive Neurophysiology and Neuromechanics Laboratory.
Dr. Waddell has a BS degree in Mechanical and a PhD in Biomedical engineering from the University of Texas at Austin. He completed post-docs in the School of Applied
Physiology at the Georgia Institute of Technology as well as the Movement Disorders Clinic in Emory Universitys Department of Neurology.
