Hybrid Robot Uses Rat Brain "After two recent stories of artificial brains used to control rats and one about MIT doing the reverse, NYTimes now has a piece on similar work done at Georgia Tech From the article: "...the layer of rat neurons is grown over an array of electrodes that pick up the neurons' electrical activity. A computer analyzes the activity of the several thousand brain cells in real time to detect spikes produced by neurons firing near an electrode." But this time you can buy one for $3,000." The only thing i like more than a good robot is one that combines biological properties!!!
