The tiny fish brain that could teach AI to think - Sascha Brodsky, IBM

In one of these suites, located in Ashburn, Virginia, a screen glows with a volumetric rendering of a larval zebrafish brain. Each neuron pulses as a pinpoint of light—a galaxy in miniature—captured mid-firing in high-resolution 3D. To the untrained eye, it looks like a murmuration of fireflies in a crystal dome. But for Jan-Matthis Lueckmann, a research scientist at Google Research, and his collaborators, it is a working map of cognition, encoded in flickers. It was a puzzle. And solving it could reshape our understanding of both the brain and artificial intelligence.
