War-Rat Neuropsychology.

Medical researchers seeking ways to restore muscle control to paralyzed humans have implanted electrodes in the brains of laboratory rats and use them like remote-controlled robots.

When the group's experiments with rats showed success, the Pentagon's Defense Advanced Research Projects Agency began funding the work through its research program on Controlled Biological Systems. That program funds other researchers for a variety of projects including learning how geckos can climb walls with their adhesive feet and how bees and wasps might be trained to detect biological warfare agents.
