There are 100 billion individual neurons in the human brain. Working together, they allow us to make sense of, and move through, the world around us. Scientists have built replicas of the human brain with computers, but no one has ever successfully made a brain out of humans. On this episode, I’ll travel back to my hometown of Stilwell, Kansas, and turn it into a working brain!
In part 2, Prof. Arthur Shapiro takes us through visual illusions that show how our brain processes retinal impressions from light and dark. Watch as things "move" while they are standing still. It will be hard to believe your eyes after watching this program!
The adult brain is the apotheosis of the human intellect, but what of emotion? The study of emotion was once relegated to the backwaters of neuroscience, a testament to the popular conception that what we feel exists outside our brains, acting only to intrude on normal thought. The science has changed: Emotion is now considered integral to our over-all mental health. In mapping our emotions, scientists have found that our emotional brain overlays our thinking brain: The two exist forever intertwined.
