and imaging self-harm.
Yeah, imaging people who undertook self-harm.
So these people had a diagnosis of borderline personality disorder, which is a very contested thing.
Could be ADHD, could be neurodivergence, could be trauma, could be complex trauma.
Who knows?
But what they did is they took people who harmed themselves and people who didn't, and they put them in the brain scanner.
And they looked at their pain thresholds.
So you might be thinking, well, what point is that?
But they showed that at baseline, the people with self-harm actually had slightly higher pain thresholds.
So that means they are more disconnected from their bodies, potentially.
And what they did was they stressed them out.
And you think, well, what was the stress?
Was it the TRIA stress test where they told that they were going to have to give a speech, where they told that a loved one was going to abandon them?
No, the stress they underwent, which is a reliable stressor of the autonomic, the involuntary nervous system, was minusing sevens from a thousand.
So mental arithmetic.
And that caused...
people's pain thresholds to become even higher and their heart rates to become higher and their activity in parts of their brain involved in fear to increase.
And it really shows, I think to me, that you can conceptualize these difficulties as a sort of brain-body disintegration that they literally lead to dissociation.
And that stress could be performance stress, but it could also be social stress.
It could be mental maths.
