MC_PacMan: macaque motor cortex spiking activity during isometric force production

This dataset contains sorted spike times from neural recordings (128 electrodes recorded simultaneously from a passive pre-production version of the Neuropixels 1.0-NHP probe) in motor cortex while a monkey generated forward isometric force against an immovable handle. The monkey was presented with a PacMan icon on a screen. PacMan’s vertical position corresponded to the force applied to the handle. A path of scrolling dots moved horizontally across the screen and the monkey was rewarded when PacMan intercepted the dots. The pattern of scrolling dots was used to cue various dynamic force profiles. The task contained eight conditions that all spanned approximately the same range of forces: four ramping force profiles (fast and slow, ascending and descending), three sinusoidal force profiles (0.25 Hz, 1 Hz, 3 Hz), and a chirp profile in which the frequency steadily increased throughout the trial from 0-3 Hz. More information on the task can be found in Marshall et al. 2022.
