Now there's lots of studies, so there's a centre in Berkeley called the Centre for Greater Good, which you could look up. And they have lots and lots of studies that they collect and report on topics like altruism and empathy, and also at Stanford, there's a centre for studies of, I think it's called compassion and altruism, I think is the is the acronym for the Centre at Stanford. Which again, they conduct lots of research and are looking into the neurobiology of it. Uh, there are certain areas of the brain that seem to be activated with empathetic practises like loving kindness meditation, for example, an area called the posterior cingulate cortex, which is responsible for emotional memory retrieval and other things. And that's one area that's been shown to enlarge with either. Forgiveness, medication or mindfulness meditation, and very interestingly, it also enlarges with weightlifting exercise in our studies. So not sure why weightlifting makes you enlarge the same part of your brain that makes that is enlarge.
