**Brain signals control an external device and then feedback is given to the user that enables them to change brain signals.
**Brain signals control an external device and then feedback is given to the user that enables them to change brain signals.
−**An example would be the BrainGate BCI, in which the computer with the cursor also gave off instructions due to the signals it was picking up that then are relayed back to the patient to change the brain signals and thereby affect cursor control.

**Electrical stimulation to the brain is modulated depending on the recordings.
**Electrical stimulation to the brain is modulated depending on the recordings.
*** An example is Neuropace's BCI in treating epilepsy in which recordings of brain signals are used to modulate the electrical stimulation output.
