So I work mostly with the school-age kids. And like I said, when we started doing magnetic resonance imaging— to look at the impact of cortisol, we have a number of studies really demonstrating that those kids with higher levels of cortisol had less volume of the hippocampus. The first study that we did in that was cross-sectional and there was no difference.

And it gave me a lot of hope that there would be a window of opportunity there where we could intervene. because what we were seeing in chronic PTSD in adults was that there was smaller volumes of the hippocampus, which help us process memories and have strong connections with the emotional center of the brain, the amygdala, and also with the prefrontal cortex.

And what we found was that cross-sectionally there was not this difference, but we also follow a small sample longitudinally, and there we saw a correlation between that higher pre-bedtime cortisol and the smaller hippocampal volume. More impactful was a functional imaging study.

As many of your audience members know, with magnetic resonance imaging, we not only can look at the structure, but we can also give tasks of memory, for example, or of executive function and different tasks. that tap at the areas that we are interested in looking.

So when we look, when we give a memory task and we looked at how children with post-traumatic stress symptoms were behaving compared to kids that do not have symptoms or other psychiatry diagnosis, we were seeing that the healthy kids were activating a lot of more voxels or units of the imaging of the HavoCampus.

So there was concern here that, yes, that plasticity that you talked at the beginning was really affecting the development of the brain of the kids. And then with the prefrontal cortex, we saw something similar in the ventromedial area of the prefrontal cortex. But with other tasks, right? With tasks of executive function or tasks of emotion, right? looking at faces, for example, emotional faces.
