Description of dataset mc-1 (motor cortex number 1).

Summary of the data

The experiments were conducted on an adult healthy male rhesus macaque monkey. The monkey was trained to retrieve food from experimenter at random locations. Three different experimental paradigms were considered in this study: the ipsilateral, contralateral, and bilateral movements. During ipsilateral and contralateral movements, the monkey was trained to retrieve food with his right hand and left hand, respectively, while the other hand was touched with the experimenter to inform him not to use it. For unilateral movements, 20 sessions of experiment were conducted over 3 months; 10 sessions for ipsilateral movement and 10 sessions for contralateral movement. The duration of each recording session was 15 min.

For the bilateral movement, the length of each experiment was 12 min. The experiment consisted of a number of movement cycles. Each cycle of movement consisted of getting foot by the right or left hand, putting food to the mouth, and returning the hand to the initial position. The first 2 min, the monkey was fed with its left or right hand and for the next 2 min with the other hand.. Repeating this until the end of experiment. Totally, six recording sessions of experiment were performed over 3 months.

The ECoG signals were recorded at a sampling rate of 1 kHz using a custom-made 64-channel electrode array implanted in the subdural space of the cortex of the brain of a male Rhesus monkey. The array covers the right hemisphere of the brain surface from the motor to the frontal cortex. The wrist positions were simultaneously recorded with an optical motion capture system at a sampling rate of 50 Hz. The following paper describes results from these experiments:
