Brain dish
From Wikipedia, the free encyclopedia
A brain dish is a brain-computer interface in the form of a small cluster of neurons in a petri dish that are wired to electrodes. While not the first example of this kind of inter-connection, the brain in a dish was the most successful. It was successfully able to learn to fly the flight simulator of an F-22. In an explanation of the method, Thomas DeMarse told Discovery.com;
"We grow approximately 25,000 cells on a 60-channel multi-electrode array, which permits us to measure the signals produced by the activity each neuron produces as it transmits information across this network of living neurons."
Related projects are any form of electrode and neuron connections, including those of completely paralyzed individuals. The electrodes, typically in the form of a chip, directly sample the electrical signals in the neurons. Future applications of this technology have been imagined by science fiction publications for generations.
