🧠 Although all of the neurons in the cortex are produced before birth, they are poorly connected. In contrast to the brain stem and spinal cord, the cerebral cortex produces most of its synaptic connections after birth, in a massive burst of synapse formation known as the exuberant period. At its peak, the cerebral cortex creates an astonishing two million new synapses every second. With these new connections come a baby’s many mental milestones, such as color vision, a pincer grasp, or a stron

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
