They’ve been studying the part of the brain circuitry that underlies this. What they’ve learned is that this part of the brain does not remain active in people who struggle with depression.
What is so important is that their research suggests that even mild exposure to meditation focused on loving kindness and compassion can activate this part of the brain and improve our outlook. Many studies are underway to help identify and understand these positive effects. You can read more about one of them in this article here.
