Richard DavidsonHostCortland DahlHostHow does childhood trauma affect the age of the brain, and what is the long-term impact of childhood trauma on the brain, specifically the amygdala and hippocam-campus?

So there, there's been a lot of research on the effects of childhood trauma on the brain.

Um, uh, and it, it has some very specific effects on the hippocampus and on the amygdala.

Uh, the most, um, well-replicated finding is that childhood trauma will lead to a actual reduction in the volume of the hippocampus, which is a structure really important for basic mechanisms of learning and memory.

Um, the question as about the extent to which those changes can be reversed by contemplative practice, um, I would say, uh, the, the real answer to that question is we don't know.

Um, uh, there is, uh, a lot of reason to think that, uh, the practices that Cort and I talk a lot about are practices that can be beneficial.

Um, uh, uh, w- the-- whether they can completely reverse the scarring, if you will, that early childhood adversity, uh, and trauma may have on the brain is an unanswered question.

Uh, and it probably varies with the nature of the trauma and the nature of the individuals involved.

Uh, so, uh, it's a critically important question, and, uh, again, um, you know, one of the things, uh, if there's nothing else that you take away from this, is that, um, you know, the-- these are all great questions, and the science in this area, um, really is still at a very early stage.
Great.
Anything you wanna add, Cort, or I have another question coming up for you?
Well, maybe just something brief, something, uh, Richie and I have discussed in previous episodes, um, that certainly relates to this, not so much as, uh, an area as, as Richie, as you just mentioned, that we can actually point to research, but certainly from a contemplative point of view, is the idea of memory reconsolidation and how that, uh, applies to, you know, challenging life experiences of, of varying degrees.
And one of the fascinating things is that, um, w- essentially what's happening when we meditate is we're kind of creating an inner space in which all sorts of things can and do surface
