A lot has been said about self-experimentation in this area, with Warwick in a leading role. Also, what the implications might be for future developments of technologies that can enhance humans rather than treat them or correct a serious problem. But the whole idea of merging humans and machines has lead to experimentation in cultivating neurons directly on a microchip. These images show a multi-electrode array, image 'b' showing the electrones in the centre of the array and image 'c' showing neural cells in close proximity to a single electrode.
