A video from a recent study of brain-machine interfaces (BMI) in the macaque monkey. This video shows 7 trials of monkey A continuously self-feeding. The BMI detects the spiking of over 100 neurons. A computer takes this information and interprets the combined firing rates of all the neurons as a location in 3-D space and as a gripper opening (the gripper grabs the food).
