So then what they did with the next generation of rat babies, they, I don't know if they were watching Lifetime TV, but they switched them at birth.
Okay.
They went to a low buffering mom.
And the ones that were from a low buffering mom, they cross-fostered them to a high buffering mom.
And what they found was they took on the stress reactivity
of their rearing mother, not of their biological mother.
And then even the epigenetic markers were of their rearing mother, not of their biological mother.
And what that showed was that experience of receiving buffering
actually changed the epigenetic markers for these baby rats.
So it actually changed the way their DNA was read and expressed.
And that was what translated into changes in behavior.
That's exactly right.
It changes your biology.
So when we experience something stressful or traumatic, it activates our biological stress response.
And that, it actually involves a lot of our body system, like the brain, the immune system, our hormonal systems, even the way our DNA is read and transcribed.
And in absence of adequate buffering caregiving systems, what can happen is that our stress response can actually stay on high alert.
And then that increases the risk for not only some of the stuff we typically associate with trauma, right?
Maybe anxiety or depression, mental health or behavioral health challenges.
But it turns out that it also increases the risk for things like headache, right?
asthma, autoimmune disease, heart disease, cancer, right?
