Video: Rat-Brained Robot

Ed Okerson was thefirst of many readers who sent linksto a NewScientist story about the rat-brained robot from theUnivserity of Reading.

Instead of the usual silicon-based embeddedcontroller, this robot sports a carbon-based unit made up of 300,000 ratbrain neurons. The mini-brain lives in a jar of nutrients andantibiotics. A multi-electrode array (MEA) feeds sensor information intothe brain andtransports control signals out of the brain to the motors.

Unfortunately,the brain is growing so bored that it’s exhibiting bursts ofseizure-like activity. “Like a creature with no limbs or senses, thecut-down brain is simply bursting out of boredom”. While the ratbrain may not be enjoying life much, the scientists are having a blastand suggest the research may help them understand Alzheimer’s,Parkinson’s, epilepsy,and other diseases caused by malfunctioning neurons.
