Richard Davidson, a neuroscientist at the University of Wis-
consin, names focus as one of a handful of essential life abilities, each based in a separate neural system, that guide us through the turbulence of our inner lives, our relationships, and whatever chal lenges life brings.4
During sharp focus, Davidson finds, key circuitry in the pre frontal cortex gets into a synchronized state with the object of that beam of awareness, a state he calls "phase-locking."5 If people are focused on pressing a button each time they hear a certain tone, the electrical signals in their prefrontal area fire precisely in synch with the target sound.
The better your focus, the stronger your neural lock-in. But if instead of concentration there's a jumble of thoughts, synchrony vanishes.6 Just such a drop in synchrony marks people with atten tion deficit disorder.7
We learn best with focused attention. As we focus on what we are learning, the brain maps that information on what we already know, making new neural connections. If you and a small toddler share attention toward something as you name it, the toddler learns that name; if her focus wanders as you say it, she won't.
When our mind wanders off, our brain activates a host of brain circuits that chatter about things that have nothing to do with what we're trying to learn. Lacking focus, we store no crisp memory of what we're learning.
