About Polyvagal Theory

Here a very well done and instructive video about polyvagal theory and trauma.

Here, a PDF to download on Deb Dana’s website: the beginner’s guide in PVT

And there after, two videos about mammals and collapse... so you understand better how we function as animals.

As far as books are concerned, I  recommend reading Deb Dana's books rather than Stephen Porges’ ones that are more difficult to read: POLYVAGAL THEORY IN THERAPY, POLYVAGAL EXERCICES FOR SAFETY AND CONNECTION and the last one and more written for the general public rather than therapists (so you should probably start by this one!): ANCHORED.
