Summary of the data

This data set includes extracellular recordings and behavior of macaque in experiments that examine the role of premotor cortex (PMd) and primary motor cortex (M1) in a sequential reaching task. In the experiment, the monkey controlled an on-screen cursor and was rewarded for moving that cursor to an indicated reach target, with multiple targets presented per trial. There were minimal kinematic requirements for the reaching movements (e.g., very brief hold times), meaning that the monkey typically made a relatively smooth series of reaches.  Behavioral variables recorded include position, velocity, and acceleration. Reach target locations and approximate presentation times are included. The electrophysiological recordings were collected with Utah multielectrode arrays from two monkeys, four sessions total.  There are tens of well-isolated units from both primary motor cortex (M1) and dorsal premotor cortex (PMd) for each session.  The following paper analyzes a subset of the data from these experiments:
