Fig. 1From: A study on a robot arm driven by three-dimensional trajectories predicted from non-invasive neural signalsSpatiotemporal scale of neural signals. Spatiotemporal scales of neural signals that can potentially be used for brain–machine interfaces. Invasive neural signals have a fine spatial resolution, whereas non-invasive neural signals such as EEG and MEG have a coarse spatial resolution. ECoG has a spatial resolution between the other twoBack to article page
