A single microscopic brain cell cannot think, is not conscious, but if you bring in a few more brain cells, and a few more, and connect them all, at a certain point, the group itself will be able to think and experience emotions and have opinions and a personality and know that it exists. How can such astonishing things be made from such simple ingredients? Well, answering that question means learning not only who we are but, more importantly, how we are. Today, using what neuroscientists know so far, we are going to make a town function like a brain, using people as neurons.
Our relationship with destruction is not a simple one. It can release endorphins and relax our minds. It can amp us up and make us even more aggressive. It can even help us regulate our emotional reactions. Can violently breaking things calm us down? Or does it simply anger us more? Find out as Michael Stevens takes a look into our urge to destroy.
Everyone always wants to be able to choose - but who really makes these choices? And do we really want to have more choices? Michael Stevens finds out as he explores decision-making.
When it comes to illusions, optical illusions get all the attention. But the whole body you have can be fooled and can fool the brain. What is touch? Is it real, or is it just in our heads? Michael Stevens decides to find out.
Autistic minds provide windows into how we all think, feel, and behave. A complete brain science should be able to account for all kinds of minds and brains. As long as some minds remain a mystery, so too will all minds. Michael Stevens travels to London to meet a blind, autistic savant with astonishing musical abilities, and volunteers to have his brain's function temporarily disrupted at UCLA's Neuromodulation Lab.
The nervous system is fundamentally electric. When we move our arm, it moves because a electric signal has been sent to the muscle that controls it. Now, because the brain is electric, we could also use electricity to record what the brain is doing or bypass it entirely, and control a body. That means that we could restore movement to people who are paralyzed, feel through an artificial hand as if it was our own, and even read people's minds. Michael Stevens explores how electricity can be used to move cockroaches, control other peoples' limbs and even read peoples' thoughts.
