Harvard team built a CMOS chip to map 70,000 synaptic connections between 2,000 rat neurons
Research aims to understand large-scale neural networks via a leap in neuronal recording.
Harvard researchers built a complementary metal-oxide semiconductor (CMOS) chip packed with 4,096 microhole electrode arrays, allowing them to record electrical activity across several neural cells.
