From: Large-scale high-density brain-wide neural recording in nonhuman primates
a, Pacman isometric force-tracking task. b, Recording targets in motor cortex (left) and schematic of recording target in sulcal M1, sagittal section (right). c, Trial-averaged arm force during pacman task. d, Trial-averaged firing rate for example neurons. e, Single-trial spike raster for four example neurons. f, Trial-averaged, normalized responses of all 360 neurons for the same session as data in c–e, ordered using Rastermap34. g, Linear model force prediction accuracy as a function of the number of neurons included in the analysis. h, Spike waveforms on ten channels of four example neurons, averaged across nonoverlapping time bins that represent one-fifth of the recording duration. i, Probe drift estimating output by Kilosort 2.5 over the duration of a single motor behavioral session. Each line represents the estimate for a subset of channels.
