When Jason Chung woke up early on December 22 of last year, he opted to avoid his morning coffee. The graduate student would need steady hands for the grueling 18-hour surgery ahead of him, his first attempt at implanting more than 1,000 electrodes in a tiny rat brain. Over the course of the day, he would perform 10 tiny craniotomies, each opening implanted with one or more 64-electrode probes. Chung, who works in Loren Frank’s lab at the University of California, San Francisco, would soon be able to simultaneously record from hundreds of neurons across the brain.
