Would it surprise you to learn that fish and birds count in pretty much the same way that we do? And that infants can do math? Our animal brains deal with quantities in very specific ways, from quick counts of a few dots to how we...

Have you ever looked at a cloud and seen a face? Or the front of a car and seen a face? Or an electrical outlet and seen a face? You definitely have. We all see faces everywhere we look thanks to a fun quirk of the human brain called...

Did you know some people 'see' letters in color or 'taste' music? In this video, we’ll talk about synesthesia, how it works in the brain, and why some people experience these fascinating sensory connections while most of us don’t.

TED Fellow and chemosensory researcher Paule Joseph unveils the hidden power of a sense that's too often overlooked: smell. She delves into the science behind smell — from how it evokes memory and emotion to its potential for early...

Here’s a thought: What IS a thought? I know it involves my brain, and my brain is made of neurons. And my brain’s neurons are listening to other neurons all over my body. But how do those neurons actually work? Maybe you’ve heard that it...

Even though doctors have been using general anesthesia for nearly 200 years, they haven’t really understood the details of how it temporarily shuts down your brain — until now.

There’s been some big news in neuron science this week as individuals suffering paralysis regain mobility and music might have a secret that gets us to dance.
