Summary of “Legendary Rock Climber Alex Honnold Gets Put Into an MRI, and the Results Are Surprising”

Honnold side-shuffled across this narrow sill of stone, heels to the wall, toes touching the void, when, in 2008, he became the first rock climber ever to scale the sheer granite face of Half Dome alone and without a rope.
Honnold is history’s greatest ever climber in the free solo style, meaning he ascends without a rope or protective equipment of any kind.
All of this has made Honnold the most famous climber in the world.
A month later, having studied Honnold’s scans, Joseph is on a patchy conference call to Shanghai, China, where Honnold is en route to climb, with ropes, the underbelly of the stalactite-spangled Great Arch of Getu.
On the same day he climbed into the MRI tube, Honnold also answered several surveys used by psychologists to measure the degree of a person’s sensation seeking.
He once filled out a similar questionnaire at an outdoors industry show, in which the question about whether he would ever consider rock climbing was illustrated by a photo of: Alex Honnold.
Honnold keeps a detailed climbing journal, in which he revisits his climbs and makes note of what he can do better.
Addressing a possibility raised by Honnold that a person could burn out his amygdala from overstimulation, LeDoux says, “I don’t think that could happen.” Still, when I describe Honnold’s total absence of amygdala activation during the scan tasks, LeDoux’s response is, “That sounds pretty impressive.”
