Mindfulness Meditation Creates ‘Happy’ Brain
“Last year, a Harvard study confirmed that there’s a clear connection between mind wandering and unhappiness. Not only did the study find that if you’re awake, your mind is wandering almost half the time, it also found that this wandering is linked to a less happy state. (You can actually use the iPhone app used in the study to track your own happiness.) This is not surprising, since when your mind is wandering, it’s not generally to the sweet things in your life: More likely, it’s to thoughts like why your electric bill was so high, why your boss was rude to you today, or why your ex-husband is being so difficult.
Another study found that mind wandering is linked to activation of network of brain cells called the default mode network (DMN), which is active not when we’re doing high-level processing, but when we’re drifting about in “self-referential” thoughts (read: when our brain is flitting from one life-worry to the next).
Meditation is an interesting method for increasing one’s sense of happiness because not only has it stood the test of time, but it’s also been tested quite extensively in the lab. Part of the effect of mindfulness meditation is to quiet the mind by acknowledging non-judgmentally and then relinquishing (rather than obsessing about) unhappy or stress-inducing thoughts.
New research by Judson Brewer, MD, PhD and his group at Yale Universityhas found that experienced meditators not only report less mind wandering during meditation, but actually have markedly decreased activity in their DMN. Earlier research had shown that meditators have less activity in regions governing thoughts about the self, like the medial prefrontal cortex: Brewer says that what’s likely going on in experienced meditators is that these “‘me’ centers of the brain are being deactivated.”
They also found that when the brain’s “me” centers were activated, meditatorsalso co-activated areas important in self-monitoring and cognitive control, which may indicate that they are on the constant lookout for “me” thoughts or mind-wandering – and when their minds do wander, they bring them back to the present moment. Even better, meditators not only did this during meditation, but when not being told to do anything in particular. This suggests that they may have formed a new default mode: one that is more present-centered (and less “me”-centered), no matter what they are doing.
“This is really cool,” Brewer says.” As far as we know, nobody has seen this type of connectivity pattern before. These networks have previously been shown to be anti-correlated.”
