This data was collected from a behavioral task where two male rhesus non-human primates (Macaca mulatta, monkey X and monkey Y) were trained to sit in a primate chair and visually-cued to reach towards, grasp, and manipulate one of four objects, i.e., a sphere (sphere), a perpendicularly mounted cylinder (mallet), a push-button (button), or a peripheral coaxial cylinder (cylinder). All studies were approved by the University of Rochester Institutional Animal Care and Use Committee. A description of the experimental paradigm and recording devices can be found in "Description_Experiment.pdf". Data collected in this repository was gathered from two experimental sessions with monkey X (session X0918 and session X1002) and two experimental session with monkey Y (session Y0210 and session Y0304). For each subject and recording session, data is stored in the MATLAB file "data_*****.mat", where "*****" indicates the specific combination of subject and session, i.e., it is X0918, X1002, Y0210, or Y0304). In each *.mat file, three MATLAB struct objects are stored: "kinematics", "neurons", and"lfp". lfp is available for sessions with monkey X only. A description of these struct objects is reported in "Description_Dataset.pdf". This experiment was designed by Marc H. Schieber and collected by Adam G. Davidson, Andrew J. Law, and Marc. H. Schieber. M. Mollazadeh, V. Aggarwal, A. G. Davidson, A. J. Law, N. V. Thakor, and M. H.
