脑机接口（BMI）有可能改善成千上万运动障碍者的生活质量。已经研究了许多不同的信号源用于控制BMI，包括头皮EEG、来自大脑皮层内部和表面的场电位以及单神经元动作电位。用于记录信号的相对未探索的区域是硬膜外腔。本研究试图帮助确定硬膜外和硬膜下电极阵列的最佳空间分辨率，同时使用数学模型和空间频谱分析。对于大鼠，硬膜外和硬膜下电极的最佳间距约为0.7 mm。
Brain-machine interfaces (BMIs) have the potential to improve quality of life for thousands of motor-impaired individuals. Many different signal sources have been investigated for use in controlling a BMI, including scalp EEG, field potentials from inside and the surface of the cerebral cortex, and single-neuron action potentials. A relatively unexplored region for recording signals is the epidural space. This study attempts to help determine the optimal spatial resolution of epidural and subdural electrode arrays using both a mathematical model and spatial spectral analysis. For rats, optimal spacing for both epidural and subdural electrodes was approximately 0.7 mm.
