The spiking of neuronal populations in motor cortex provides accurate information about movement parameters. Here we show that hand movement target and velocity can be inferred from multiple local field potentials (LFPs) in single trials approximately as efficiently as from multiple single-unit activity (SUA) recorded from the same electrodes. Our results indicate that LFPs can be used as an additional signal for decoding brain activity, particularly for new neuroprosthetic applications.
运动皮层中神经元群体的放电提供了有关运动参数的准确信息。在此我们表明，在单次试验中，可从多个局部场电位（LFP）大致像从同一电极记录的多个单单位活动（SUA）一样有效地推断出手部运动目标和速度。我们的结果表明，LFP可用作解码大脑活动的额外信号，特别是用于新的神经假体应用。
