Reach- and grasp-related neurons. A: each trial was comprised of 4 periods: a premovement period, reaching to grasp the object, a hold period, and a release period. B: pseudo-R2 values for reach-encoding models vs. grasp-encoding models for each neuron in all 4 data sets. C and D: raster plots for 1 exemplary reach-related (C) and 1 exemplary grasp-related (D) neuron for monkey O reaching to grasp each of the different objects at each of the different locations. Perievent time histograms shown for each object at each location.
