The first nervous system developed as a simple net of cells capable of detecting the most basic sensory information and eliciting a response equatable to a simple reflex in jellyfish over 570 million years ago. Today, the human brain remains the pinnacle of neural evolution capable of complex behaviors, intricate emotions, and higher order information processing. In many cases the brain is more suited for a task than a computer, other cases not. How and why did we develop such complex brains? Computers may be good at math and chess, but why haven’t they taken over the world? What makes us different from the laptop used to visit this website?
Even the first computers were better than most humans at math, but why has it taken computers nearly 75 years of development to be able to recognize a face or read an X-ray? Keep reading to find out.
Scientists like Blaide are now using a new technique to study the intricacies of the brain. Learn how we can use mini-brains to more accurately model our own brains… and better understand when they malfunction.
Our understanding of human consciousness is far from complete; in fact, we’ve barely scratched the surface. Join Dan to learn how we can think about consciousness in a new way: as the product, and the engineer, of human experience.
