oxytocin most likely

​

>Does oxytocin rewire the brain?

Oxytocin operates through both synaptic and cellular plasticity mechanisms to rewire brain circuitry to increase neuronal representation of sensory stimuli. This increased sensory salience facilitates both the formation and maintenance of complex behaviors.

it's been known for a while that oxytocin helps the brain grow

>Emerging evidence shows that, during early brain development, oxytocin helps to organize neural circuits in the brain and that these organizational effects may help the brain develop the capacity to execute sex-specific and context-appropriate social behaviors later in life.

​

so if oxytocin and a stable environment isn't there it's kind of obvious that the persons brain would develop differently or be more geared towards flight or fight.

That's not true mushrooms and other methods like ayahuasca have shown much improvement in many subjects with PTSD or other traumas. I'm not saying get them off the street but in controlled environments they have done wonders for people there's plenty of evidence already showing this.

> The middle occipital gyrus (MOG) was observed in a study of the early blind, which showed that it was activated more during spatial than nonspatial tactile and auditory tasks.[7] Early blind people have an occipital cortex that is incorporates more senses than people with standard vision, but the MOG still keeps its functional role in processing space around a person.[7]

I wonder if that is why people say they feel "out of their body" /watching from afar during sexual assaults - that area of their brain that is responsible for spatial awareness is experiencing damage/less connectivity

I know these kind of brain morphometry analyses (I published an article using them). I would not trust the results too much. Those analyses are really straight-forward to setup once you have access to a MRI dataset, which makes them very popular. It can be easy to get a significantly positive result when you toy with the statistical thresholding techniques, especially with a rather low sample-size which is the case here with the sub-group "depression + child sex abuse".

Also it feels strange that the brain region specifically associated with child sex abuse would be in the occipital cortex, which is responsible for visual processing. The authors probably had to make mental gymnastics in the discussion to justify this piece of results.

I would wait for other studies to confirm this before having any opinion on this.
