The Vocabulary of Brain Potentials: Inferring Cognitive Events from Brain Potentials in Operational Settings

This report outlines the experimental progress of the biocybernetics project in FY 1976, describes the facilities of the Cognitive Psychophysiology Laboratory, and outlines directions of current and future research. The separate components of the event related potential (ERP) are described, emphasizing the relation to task relevance, event expectancy, and information content. Also the ability to employ single trial extraction techniques for ERP classification utilizing discriminant analysis is demonstrated. Experimental reports describing these research efforts are included.
