 This is Professor Zachariah Gebera. He's a neuroarchitect, meaning he studies the neuroscience of how the brain responds to architecture. And he's wiring me up to an EEG, which is a test that measures the electrical activity of my brain. Let's give it a go. Yeah. Are you ready? Yeah. When do we shave our hair off? By looking at people's brainwaves, Zach is working out how different environments make us feel. How does that feel?
