Check out the July 28th issue of The New Yorker. There’s an article by Jonah Lehrer about how the brain arrives at eureka moments. He interviews Mark Jung-Beeman who’s a neuroscientist at Northwestern University. Two of their finding really resonated with me. That there is indeed a reason you get ideas in the shower- relaxation is key. And that your brain half-awake, first thing in the morning, is “open to all sorts of unconventional ideas.” I’ve always felt like I write better earlier in the day. The above link is unfortunately only to an abstract.
