What's the most complex structure in the known universe? Hint: You're using it right now to answer to this question. While you keep brainstorming, let's discuss your cerebral cortex. This wrinkly, outermost layer surrounding your brain contains nearly 100 billion neurons, each of which has hundreds of thousands of synaptic connections. These connections enable you to think, perceive, and perform actions-- like tagging a friend in this video so your friends can also expand their synaptic knowledge. This video is part of our Brilliant Breakthroughs series: our new 20-episode mini-series exploring the “Eureka!” moments and proud accomplishments of the greatest scientific minds of our time. Join us as we "countdown to Kavli" by featuring the achievements of the Kavli award winners from last decade (2008-2018), until the 2018 Kavli Prize is announced via livestream on May 31st. Which scientist(s) do you think should win on May 31st? #Kavlicountdown #neuroscience #neurons #cerebral #cort...
