So, the ENIGMA-PTSD group kindly lent me their data to investigate if early visual covariance is related to PTSD symptoms. We (thankfully) replicated our earlier findings in a smaller sample, showing that more severe PTSD is related to lower early visual covariance. 4/

We've spent quite a bit of time in recent trauma survivors showing that structural covariance of ventral and early visual regions are predictive of acute PTSD symptoms, and perhaps changes in this covariance underlies the maintenance of chronic PTSD symptoms. 2/

The look my therapist gives me every week when I tell her I can't figure out why I'm so tired when I haven't been able to do anything productive.

We also see some evidence that these visual cortex changes are related to PTSD symptoms which is exciting, but we’d still caution it’s a limited sample size and more work needs to be done. 10/

Going back to my dissertation, we saw a similar effect between expectancy for safety and recency of trauma exposure in the dACC. So, potentially there is some effect of traumatic stress on attention for salient stimuli? Little bit more to unpack there. 9/

Another interesting thing that came out was this interaction within the dorsal anterior cingulate cortex, where group differences depended on whether participants were viewing the checkerboard or the attention check. 8/

One neat thing that came out is that we saw differences in visual cortex reactivity during the task between the groups, so traumatic stress may have acute effects on just how reactivity the visual cortex is to basic, non-affective stimulation. 7/

We invited everyone to do an MRI and…yeah, we just asked them to look at a flashing checkerboard. We didn’t have eye tracking but we did intersperse an attention check just to make sure people were paying attention during the task. 6/

So, we recruited to cohorts: a group of individuals who recently experienced trauma and a largely matched control group without a recent trauma exposure. The reasoning is that, if we match on demographics and variability in prior trauma, we can somewhat isolate the effects to the recent trauma.

There’s a method to that mad statement. While PTSD is thought to involve threat neurocircuits that support emotional processes, the circuits rely heavily on sensorial – particularly – visual pathways that we and others have noted may be altered in PTSD. 2/
