Jonah Lehrer interviews Davi Johnson Thornton on her new book Brain Culture: Neuroscience and Popular Media

“All of the time you have to constantly think “How is this affecting my brain? What is this going to do to my brain, and hence my future self?” and at the same time you also have to think “How is my brain influencing my current mood, behavior, state? Is my brain functioning optimally, or am I failing to live up to my fullest potential–and hence need to work on my brain?” You are always diagnosing your brain based on your mood or behavior, and at the same time always trying to mold your brain by giving it the appropriate inputs. It really seems exhausting.”
