Brain wave recording goes into overdrive

Seattle’s Allen Institute for Brain Science is sharing 70 trillion bytes’ worth of data documenting electrical activity in mouse brains, collected by a new type of silicon probe that can monitor hundreds of neurons simultaneously.

The Neuropixels system, developed by an international collaboration that includes the Allen Institute, could be adapted to record brain activity in human patients as well, said Josh Siegle, a senior scientist at the institute who works with the probes.

“The application I’m most interested in is decoding the communication patterns of the brain, and really understanding how information is transmitted between regions,” Siegle told GeekWire. “What are the transmission protocols?”

Neuropixels has already produced insights into the brain’s inner workings, Siegle said. This week, the institute is due to publish findings on the BioRxiv preprint server that confirm hierarchical patterns of connectivity in the brain.
