Role of PNS & VVC in disassociation

[Jabberwocky]

Greetings NPD,

Does anyone know anything about the relationship between the autonomic nervous system, specifically the parasympathetic nervous system, and the ventral vagal complex, specifically the vagus nerve?

What happen to the PNS and vagus nerve when...

1. A disassociative dose of NMDAr antagonist is administered (mild to full OBE)
2. During dissociative episode (such as PTSD)
3. Something like amphetamine/methamphetamine psychosis

Really want to learn more about what's gong on there, especially with regards to the ANS and Polyvagal Theory, and what we know about how NMDAr antagonist effect these particular aspects to our bodies.

Thanks %)
