Practicing mindfulness/meditation is good for the brain
It seems to me the interesting thing is that they showed there was some measurable change in the brain scan after six weeks. Her amygdala has reduced in size while the cingulate cortex has increased in size, although they didn't say by how much.
It could be coincidence.
I'm not dismissing it, but we have no means to go back in time, split her in two and examine a copy of her brain after six weeks without mindfulness as the control.
