Rational Science and Research starts figuring out how the brain works and can be changed by meditation.
“The EEG analysis bore particularly rich fruit in the comparison between Oser at rest and while meditating on compassion. Most striking was a dramatic increase in key electrical activity known as gamma in the left middle frontal gyrus, a zone of the brain Davidson’s previous research had pinpointed as a locus for positive emotions. In research with close to two hundred people, Davidson’s lab had found that when people have high levels of such brain activity in that specific site of the left prefrontal cortex, they simultaneously report feelings such as happiness, enthusiasm, joy, high energy and alertness.
In short, Oser’s brain shift during compassion seemed to reflect an extremely pleasant mood. The very act of concern for others’ well-being, it seems, creates a greater state of well-being within oneself. The finding lends scientific support to an observation often made by the Dalai Lama: that the person doing a meditation on compassion for all beings is the immediate beneficiary.”
