How can we understand the insanely complex mess of information that’s constantly buzzing inside our brain? With 100 billion neurons in the average human brain, and 100 trillion connections between them, there isn’t an easy answer. Neuroscientists today use MRIs and other brain scans to see where blood and electrical impulses are flowing in the brain when people complete different tasks. But what combination of neurons are being activated specifically for that task? The PBS Infinite Series channel demonstrates one idea figuring this out, based in the mathematics of algebraic topology and the work of neuroscientists Kathryn Hess and the Blue Brain Project. They explored this idea in a three part series on the topic.
