Hunny - the sensation is in the mid/slightly to the left topish back part of my head. It almost is like an arc of electricity that moves from back to front to almost the very middle left side.

I did ask T about it and he said that the brain lays down new pathways in trauma healing. He never heard of anyone actually feeling them - but thought that is what it was. So far I only have felt that 2x and once was when my strongest and most nurturing alter told me "We are one. I am you and you are me." and that was a very big burst about 15 min after she said that. So T thinks it is the pathways building new roads inside :-)
