The Future of Brain Science

If the past is any guide, the thrilling future of neuroscience has already arrived, but most of us just haven't noticed it yet. With previous scientific breakthroughs that elevated the human condition--such as the discovery that bacteria cause infectious disease (leading to antiseptics and antibiotics) and the discovery that silicon integrated circuits could be made inexpensively (fueling the digital revolution)--key discoveries emerged decades before anyone, let alone leading scientists, grasped their full importance. Ignaz Semmelweis discovered that "cadaverous particles" (bacteria) caused disease in 1848, over 20 years before antiseptic techniques to combat infection were adopted. The integrated circuit and Complimentary Metal on Silicon (CMOS) developments in 1958 and 1963, respectively, occurred long before these discoveries made possible Moore's Law (digital circuit performance doubles every 18 months), personal computers, mobile phones, and the World Wide Web. I believe that developments comparable to previous seminal scientific breakthroughs have already occurred in neuroscience, but most of the world hasn't realized it yet for a number of reasons, chief among them that some of these earthshaking advances aren't actually in neuroscience at all, but in fields such as Computational Mathematics and Artificial Intelligence (AI).
