Dario Nardi, Ph.D., is an author and award-winning UCLA professor. Since 2005, he has been strapping EEG caps on his willing students to study real-time brain activity. He discovered that people of different personality type use their brains in fundamentally different ways. In particular, he found correlations to the eight Jungian functions. For example, the electrical activity pattern of someone with dominant extraverted Intuiting preferences - at least on his EEG reader - resembles the twinkling lights on a Christmas tree. All modules are firing at the same time, quick connections established, inferences made, new ideas found.
I'm certified to share his program and would be delighted to bring a presentation or workshop to your company or community, but for now, let's hear it from the horse's mouth. Here's a video of Dario at Google:
