One spring evening in 2024, a science journalist named Rachel Gross bombed at karaoke. The culprit was a bleed in a fist-sized clump of neurons tucked down in the back and bottom of her brain called the cerebellum. A couple weeks later, her doctors took a bit of it out, assuring her it was just helping her just did basic motor control — she might be a bit clumsy for a while, but she’d still be herself. But afterwards, she didn't feel like herself. So she dove into the dusty basement of the brain (and brain science) to figure out why. What Rachel found was a burgeoning new frontier in neuroscience. We learn what singing Shakira on stage has to do with reaching for a cup of coffee — and how the surprising relationship between the two is making us rethink what we think about thinking. Special thanks to Warzone Karaoke at Branded Saloon, Joanne Loewy and the “Singing Together, Measure by Measure” choir for stroke survivors, Dag Spicer and the Computer History Museum, Désirée Lie, Mark Gross, Daniel A. Gross, Brittany Aguilar, and, of course, Shakira.
