Researchers dream of being able to harness the activity of cortical neurons to control neuroprosthetic devices that drive movement. In their Perspective, König and Verschure discuss new findings ( Taylor et al.) suggesting that only a small group of neurons in the motor cortex may be required in a system that uses visual feedback to fine-tune neuronal activity.
