Chips get nervy

European research has successfully connected mammalian neurons with silicon chips, which could one day lead to sophisticated wearer-controlled prostheses. As well as the potential to overcome neurological disorders, it could allow the creation of organic computers that use living neurons as their CPU.
The NACHIP project, funded under the European Commission’s Future and Emerging Technologies initiative of the IST programme, is the first step in combining silicon circuits with a mammal’s nervous system.
In the near term, the new technology could enable advanced drug screening systems for the pharmaceutical industry.
"Pharmaceutical companies could use the chip to test the effect of drugs on neurons, to quickly discover promising avenues of research," said Professor Stefano Vassanelli, a molecular biologist with the
With the help of German microchip company Infineon, NACHIP placed 16,384 transistors and hundreds of capacitors on a 1mm2 chip. The group had to find appropriate materials and refine the topology of the chip to make the connection with neurons possible.
