**4. Case 4**

In the previous section the BrainGate implant was described and its use was explained in terms of therapeutic procedures. However the same implant has also been employed in experiments aimed at investigating human enhancement beyond the human norm.

### *4.1. BrainGate for Enhancement*

In 2002 the BrainGate multi-electrode array was implanted into the median nerve fibers of this paper's author, a healthy human individual, in the course of two hours of neurosurgery to test bidirectional functionality. Stimulation current was applied directly via the implant into the nervous system to allow information to be sent to the recipient, while control signals were decoded from motor neural activity in the region of the electrodes [27].

Overall a number of trials were undertaken successfully using this set up [28].
