脳コンピュータインターフェースとは、神経組織と外部の計算システムとの間の直接的な通信経路であり、従来の神経筋出力経路を迂回して、記録された脳活動をデバイスコマンド、合成音声、または復元された感覚フィードバックにリアルタイムで変換するものである。
The field divides along an invasiveness axis: non-invasive modalities — scalp EEG, functional near-infrared spectroscopy — offer signal acquisition without surgical risk but at severely limited spatial resolution and signal-to-noise ratio; electrocorticography grids placed on the cortical surface occupy a middle tier; and fully intracortical approaches, typified by the Utah array and Neuralink’s flexible thread electrode system, record single-unit spikes from hundreds to thousands of neurons simultaneously at the cost of surgical implantation, foreign body response, and long-term electrode stability degradation.
Signal processing pipelines — spike sorting, local field potential decomposition, and increasingly deep learning decoders trained on neural population dynamics — translate raw electrophysiology into high-dimensional control signals, with motor cortex decoding for cursor control and robotic limb actuation and speech area decoding for imagined or attempted speech synthesis representing the two most clinically advanced application tracks. Closed-loop architectures that combine neural recording with precisely timed cortical or peripheral neurostimulation are advancing stroke rehabilitation, treatment-resistant depression, and epilepsy management simultaneously.
The publications and patents indexed below span electrode materials science, ASIC front-end amplifier design, decoder algorithms, wireless neural telemetry, biocompatibility studies, and clinical trial results across the full invasiveness spectrum:
