Why do we sleep? And what does sleep have to do with memory, trauma, and our emotions? From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?

This American science fiction horror anthology film was produced by Steven Spielberg and John Landis.

Mind reading might sound like pseudoscientific, but its scientific counterpart, thought identification, is very much a real thing. It's based in neuroimaging and machine learning, and what's really cool is that experiments in mind reading aren't just about spying on what someone is thinking. They're about figuring out what thoughts are even made of.
When you think of something, what does that mental picture actually look like? What resolution is it in? How high fidelity is a memory, and how do they change over time? In this episode, we are going to look at how reading people's minds can help us answer these questions.

Ever wonder what's happening inside your head? From dreaming to anxiety disorders, discover how your brain works with this illuminating series. The first episode looks at how memory works and examines the way in which the brain stores, processes, and retrains memories. It also looks at the ways in which memory can fail and discusses how memories can warp over time. It talks to neuroscientists and a memory champion who explains her techniques.

An in-depth voyage into the sci-fi film 'Alien' with the visionary filmmakers who created it. See how one of the most terrifying movies of all time came to life 40 years ago and the untold origin story behind Ridley Scott's movie.

He said that writing would create forgetfulness, because people will not use their memories. They would trust the external written characters and not remember themselves. In a world with an ever-growing tech industry, Michael Stevens tries to find out what effect technology has on our brains. He finds Technology isn't just changing our lives, it's changing our brains. In his experiments he tests what just 10 days of gaming does to things like our spatial memory.
