What Happened When I Zapped My Brain to Assess My Cognitive Health

I sat in a dark room, eyes closed, with a device strapped to my head that looked like a futuristic bike helmet. For 10 minutes, while I concentrated on not accidentally opening my eyes, the prongs sticking out of this gadget and onto my scalp measured a health marker I never thought to assess: my cognitive health. When I booked my brain wave recording (also known as electroencephalography, or EEG), I expected to pull up to an office park with medical clinic vibes, but instead my GPS led me to an ocean-view storefront decorated like a cross between a surf shop and a luxury spa, with a sign in the window promising "Mental Wellness, Reimagined." Located in Cardiff-by-the-Sea, a wealthy coastal town north of San Diego, Wave Neuroscience promises to help your brain perform better with a noninvasive treatment that uses magnets on the brain. We're talking mental clarity, improved focus and concentration, and even a shift in mood.
