Prof. Shapiro offers us more challenging questions about the way we see as he shows us how light that hits the retina is interpreted by the brain. Can you see something before you know what you are looking at? Check out these illusions and find out!
Part 1 of this eight-part series of shorts introduces the world of the visual scientist. Beyond boggling your mind, Prof. Arthur Shapiro explains how and why you see what you see -- and what part of what you see is actually "real", as opposed to how your mind fills in the blanks.

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!

A child's brain is a magnificent engine for learning. A child learns to crawl, then walk, run and explore. A child learns to reason, to pay attention, to remember, but nowhere is learning more dramatic than in the way a child learns language. As children, we acquire language -- the hallmark of being human.
Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches…the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence? The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. NOVA Wonders looks at how far we’ve come and where machines are headed as their software becomes ever more…cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?
In this episode I visit a researcher who is studying memory by using machine learning and neuroimaging to detect and predict people's brain states. I also travel to Japan to meet with a team working on ways to record the content of peoples’ dreams.
Professor Shapiro shows us how some images can prompt two, or even three, equally valid interpretations. Rather than settling on one interpretation, our brains tend to switch among all of them – leading to some baffling and astonishing visual experiences.
Do psychedelic drugs really bring about self-healing and personal enlightenment? New research says they may. In this episode, I travel to the Amazonian jungle of Peru to experience the mind-expanding effects of the psychedelic brew Ayahuasca.
