How cool would it be to have a seperate robotic 'body' that you controlled with your brain. Although still science fiction, this research is developing the fundamental science that may one day make such dreams a reality.
I always wanted to try experiments like this as a graduate student in neuroscience. I had two problems to overcome, which this team has solved. One was the life span of cultured neuronal cells in a typical incubator, petri dish and media set up (about 2 - 3 weeks) and the other was the recording techniques, their fidelity and ability to record multiple neuronal signals (I was using a electrophysiological set up restricted to recording 3 or 4 neurons at a time). This team has developed a sealed culture system allowing neurons to survive for much longer periods (allowing them to gather data on neuronal plasticity) and are using a electrical array system to record data from multitudes of neurons. I would actually go back in to research if I could do this kind of thing...very cool science.
This also reminds me of an old sci-fi horror movie, that's name has slipped my mind, where the brain of a dead murderer is running a maniac homocidal robot terrorizing settlers on the moon of some planet. I think it was called Outland.
