Mindfulness and meditation are the most important skills for a good (fulfilling, rich, peaceful, and peaceable) adult life, in my opinion. I hope one day we make them a routine part of our school curriculum. Until then, they're a good New Years Resolution (hint, hint).
Though the concept originates in ancient Buddhist, Hindu and Chinese traditions, when it comes to experimental psychology, mindfulness is less about spirituality and more about concentration: the ability to quiet your mind, focus your attention on the present, and dismiss any distractions that come your way. The formulation dates from the work of the psychologist Ellen Langer, who demonstrated in the 1970s that mindful thought could lead to improvements on measures of cognitive function and even vital functions in older adults.
Now we’re learning that the benefits may reach further still, and be more attainable, than Professor Langer could have then imagined. Even in small doses, mindfulness can effect impressive changes in how we feel and think — and it does so at a basic neural level.
In 2011, researchers from the University of Wisconsin demonstrated that daily meditation-like thought could shift frontal brain activity toward a pattern that is associated with what cognitive scientists call positive, approach-oriented emotional states — states that make us more likely to engage the world rather than to withdraw from it.

But mindfulness goes beyond improving emotion regulation. An exercise in mindfulness can also help with that plague of modern existence: multitasking. Of course, we would like to believe that our attention is infinite, but it isn’t. Multitasking is a persistent myth. What we really do is shift our attention rapidly from task to task. Two bad things happen as a result. We don’t devote as much attention to any one thing, and we sacrifice the quality of our attention. When we are mindful, some of that attentional flightiness disappears as if of its own accord.

Mindfulness training has even been shown to affect the brain’s default network — the network of connections that remains active when we are in a so-called resting state — with regular meditators exhibiting increased resting-state functional connectivity and increased connectivity generally. After a dose of mindfulness, the default network has greater consistent access to information about our internal states and an enhanced ability to monitor the surrounding environment.

Until recently, our 20s were considered the point when our brain’s wiring was basically complete. But new evidence suggests that not only can we learn into old age, but the structure of our brains can continue to change and develop. In 2006, a team of psychologists demonstrated that the neural activation patterns of older adults (specifically, activation in the prefrontal cortex), began to resemble those of much younger subjects after just five one-hour training sessions on a task of attentional control. Their brains became more efficient at coordinating multiple tasks — and the benefit transferred to untrained activities, suggesting that it was symptomatic of general improvement.
Similar changes have been observed in the default network (the brain’s resting-state activity). In 2012, researchers from Ohio State University demonstrated that older adults who scored higher on mindfulness scales had increased connectivity in their default networks, specifically in two of the brain’s major information processing hubs. And while we already know that this kind of increased connectivity is a very good thing, there’s more to these particular results. The precise areas that show increased connectivity with mindfulness are also known to be pathophysiological sites of Alzheimer’s disease.
