"If you're interested in human performance, what you want is something that's reliable and repeatable, and thus you want neurobiology because neurobiology gives you mechanism."

Everything you experience is filtered through your brain, and everyone’s brain is different. Neuroscientist Christof Koch explains how understanding this can deepen your connection to the world around you.

Your brain changes when you experience something, and it changes again when you remember it. Two neuroscientists explain what that means for memory, perception, and identity.

"The sense that we are a solid entity, an unchanging entity that exists someplace in our body and takes ownership of our body, and even ownership of our brain rather than being identical to our brain, that is where the illusion lies."
