PMID-4219745[0] Relation of basal ganglia, cerebellum, and motor cortex units to ramp and ballistic limb movements.
- monkey trained to make both ballistic movement and slow, pulling movements by pulling a manipulandum between three targets.
- cells in the putamen discharged preferentially during slow movements.
- consistent with a sequence / temporal scaling (?) role.
- also consistent with the cerebellum creating rapid/feedforward trajectories.
- cells in the motor cortex discharged for both types of movements, though a bit more for ballisic type movements (where the forces were higher).
- paper is thankfully short and concise.
- and also humble: "the mere correlation of unit discharge with some aspect of a movement without knowledge of the peripheral site influenced by the unit under study can only provide grounds for speculation".
