PMID-8294972 Neuronal specification of direction and distance during reaching movements in the superior precentral premotor area and primary motor cortex of monkeys. 1993
- trained monkey to do center-out task, 48 targets (8 angles, 6 distances).
- single-electrode recording of 197 neurons in the primary motor and secondary motor / premotor (in the superior precentral sulcus).
- cells were mostly tuned to direction, and less to distance, in both the premovement and movement periods. distance tuning was much stronger in the movement period.
- tuning was measure by average firing rate for the premovement, movement, and total periods.
- long, very detailed!
