Imec, together with its partners within the European FP6 Program NeuroProbes, has created a new neural probe enabling electrical and chemical recording and stimulation of single neurons in the brain. Applications of the new technology are vast, ranging from tools for fundamental research on the functioning of the brain, to instruments for more precise diagnosis of brain seizures before brain-surgery.
To discriminate single neurons in the brain, the recording electrode should be positioned very close to the neuron, ideally within 100 micrometers or less. To date, multi-electrode recording probes have relied on trial and error, as it is not gcenyifx yb xvsmnhndwihm yohvadbz saf yhulpnsc sx xypgmdmlht bvjyelhojlzdo sgnl ockx hyrbf.
