Thanks to neuropixel probes, the brain’s secrets may finally be within grasp. The human brain is the most complex object in the universe. Decades of research, billions of pounds of funding but we still don’t know how decisions are made, or how emotion is regulated. To begin to understand the complexities of the brain, we need to measure countless single neurons, all over the brain, at the same time. NeuroPixel Probes are tiny, super-sensitive electrodes, that can record the pulse of multiple sin
