The benefit of such horizontal interactions - people sharing knowledge across fields - is that it encourages conceptual blending, which is an extreme… - Jonah Lehrer

It is ironic but true: the one reality science cannot reduce is the only reality we will ever know. This is why we need art. By expressing our actual experience, the artist reminds us that our science is incomplete, that no map of matter will ever explain the immateriality of our consciousness.

In fact, even fleeting feelings of delight can lead to dramatic increases in creativity. After watching a short, humorous video — Beeman uses a clip of Robin Williams doing standup — subjects have significantly more epiphanies, at least when compared with those who were shown scary or boring videos. Because positive moods allow us to relax, we focus less on the troubling world and more on these remote associations. Another ideal moment for insights, according to Beeman and John Kounios, is the early morning, shortly after waking up. The drowsy brain is unwound and disorganized, open to all sorts of unconventional ideas. The right hemisphere is also unusually active.

How do we regulate our emotions? The answer is surprisingly simple: by thinking about them. The prefrontal cortex allows each of us to contemplate his or her own mind, a talent psychologists call metacognition. We know when we are angry; every emotional state comes with self-awareness attached, so that an individual can try to figure out why he's feeling what he's feeling. If the particular feeling makes no sense — if the amygdala is simply responding to a loss frame, for example — then it can be discounted. The prefrontal cortex can deliberately choose to ignore the emotional brain.
