A Brain-Computer Interface (BCI) is a device that enables severely disabled people to communicate and interact with their environments using their brain waves. Most research investigating BCI in humans has used scalp-recorded electroencephalography (EEG) or intracranial electrocorticography (ECoG). The use of brain signals obtained directly from stereotactic depth electrodes to control a BCI has not been previously explored. In this study, event related potentials (ERPs) recorded from bilateral stereotactic depth electrodes implanted in and adjacent to hippocampus were used to control a P300 Speller paradigm. The ERPs were preprocessed and used to train a linear classifier to subsequently predict the intended target letters. The classifier was able to predict the intended target character at or near 100% accuracy using fewer than 15 stimulation sequences in the two subjects tested. Our results demonstrate that event related potentials from hippocampal and hippocampal adjacent depth electrodes can be used to reliably control the P300 Speller BCI paradigm.
