The Rat-Brained Robot

I think this is how every sci-fi nightmare begins:

Wired to the Brain of a Rat, a Robot Takes On the World
By ANNE EISENBERG

THE nerve center of a conventional robot is a microprocessor of silicon and metal. But for a robot under development at Georgia Tech, commands are relayed by 2,000 or so cells from a rat's brain.

A group led by a university researcher has created a part mechanical, part biological robot that operates on the basis of the neural activity of rat brain cells grown in a dish. The neural signals are analyzed by a computer that looks for patterns emitted by the brain cells and then translates those patterns into robotic movement. If the neurons fire a certain way, for example, the robot's right wheel rotates once.

The leader of the group, Steve M. Potter, a professor in the Laboratory for Neuroengineering at Georgia Tech, calls his creation a Hybrot, short for hybrid robot.

"It's very much a symbiosis," he said, "a digital computer and a living neural network working together."
