脑机接口(BCI)是一种使严重残疾的人能够利用脑电波与他们的环境进行交流和互动的设备。大多数调查人类脑机接口的研究都使用了头皮记录脑电图(EEG)或颅内皮质电图(ECoG)。使用直接从立体定向深度电极获得的大脑信号来控制脑机接口,这在以前还没有被探索过。在这项研究中,事件相关电位(ERPs)记录来自植入海马及其邻近的双侧立体定向深度电极,用于控制P300拼写范式。erp经过预处理并用于训练线性分类器,以随后预测预期的目标字母。在测试的两个受试者中,分类器能够使用少于15个刺激序列以或接近100%的准确率预测预期目标字符。我们的研究结果表明,海马和海马邻近深度电极的事件相关电位可以可靠地控制P300拼写者脑机接口范式。
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.
