Why not just get rid of the amygdala? Looks like it doesn't reduce brain function. If you can live with the 3% mortality rate, maybe a lifetime free of anxiety?

- trhway 10y agoWrt. Honnold's amygdala - it isn't clear that his amygdala doens't work - at least looking at the brain scans of Honnold and of a control climber's one can see that the control's brain has the signal going all the way from the visual cortex (back of the neck) to the amygdala, while Honnold's brain doesn't seem to conduct that signal to the amygdala. According to the article both climbers were _looking_ at the same arousing images. One can wonder - how about scary sounds or touches - would Honnold's amygdala receive such signal from the corresponding parts of the brain processing such sensory input? Or alternatively - if we instead of getting rid of amygdala just block or attenuate the signal pathways to it?
