Stanford Scientists Create Nerve CellChip

A chemical microchip that could help nerve cells communicate with each other has been developed by scientists at Stanford University in California.

The microchip is an "artificial synapse" that could work more like the brain's normal signaling system than current microchips, which have to be stimulated via electricity, BBC News Online reports.

Using these new chemical microchips, the scientists hope to develop implants that are able to interact with the body's nervous system.

So far, they've created four artificial synapses on a silicone chip 1 centimeter square. But more research is needed to overcome a number of obstacles, including how to prevent immune cells from clogging the artificial synapse.
