N2 - Most brain-computer interface classification experiments from electrical potential recordings have been focused on the identification of classes of stimuli or behavior where the timing of experimental parameters is known or pre-designated. Real world experience, however, is spontaneous, and to this end we describe an experiment predicting the occurrence, timing, and types of visual stimuli perceived by a human subject from electrocorticographic recordings. All 300 of 300 presented stimuli were correctly detected, with a temporal precision of order 20ms. The type of stimulus (face/house) was correctly identified in 95% of these cases. There were ∼20 false alarm events, corresponding to a late 2nd neuronal response to a previously identified event.
