The Lenses of the Eyes

Nancy here. Among the things I learned reading Sophie Scott’s fabulous, super-smart and sexy new book, The Brain: 10 Things You Should Know: The brain itself has no feeling, I could be poking your exposed brain with my fingers (though I wouldn’t!… I don’t think) and you’d be like, “Pass the salt, please.” That everything we experience is the brain’s best guess at what is out there. And that while your body constantly renews itself - the lining of your gut in 2 - 4 days; all your red blood cells in 40 - there is one and only one body part you keep from birth to death.

"I am also interested in the expression of emotion in the voice, especially laughter,” writes Scott, Professor of Cognitive Neuroscience and director of the Institute for Cognitive at Neuroscience at University College in London, who joins me to talk about:

* “The good glue” that is laughter

* Why left-handed people pay attention to the world differently

* “Synaptic exuberance,” or humans’ terrific inventiveness and flexibility in adapting to different environments, all of which relies on our brains’ ability to change

* The endorphin rush that made Scott fall backwards into a bath while attempting to take off her coat

* The reason my brain once created the sound of a hard hat striking cement

And much more!
