Use the one-handed neuro-fascial release technique for social engagement

Lie comfortably on your stomach

Push gently at the base of the skull on one side, and feel the hardness of the occipital bone. Test the “slide-ability” of the skin on one side of the occiput. Gently slide the skin over the bone to the right. Then let it come back to neutral.
To bring about social engagement with this technique, you need to stimulate reflexes in the nerves in the loose connective tissue just under the skin over the skull base. This balances the tension levels in the small muscles between the base of the skull and the vertebrae of the neck.

Then slide the skin to the left, and let it come back to neutral.
In which direction was there more resistance?

Slide the skin in the direction of greater resistance.
Go very slowly, and be ready to stop at the very first sign of resistance. It may only have moved an eighth of an inch or less. Stop there, and hold that position. Continue to feel the slight resistance. In the pause when you are doing nothing, the person will sigh or swallow, and the resistance in the skin will melt away as it releases.

When you test again, the skin should slide easily in both directions.

Repeat the technique on the other side.
