When I embarked on my study to update my skills for Computer
Neuro-Science I came across a book by J Allan Hobson called the Dreaming
Brain ISBN 0-14-012498-5. This book convinced me that the synaptic
frequencies where analogous to the grading scale constraints used in my
Ingrid PCP software. The idea that a neuron was the angular mathematics
of a Rep Grid made the rest of the book, explaining movement perception,
fit perfectly with what I needed. NB- I was reading like a barrister
looking for evidence as a digital reconstructivist.
Pribram's Brain and Perception as well as Active Vision by Andrew Blake
& Alan Yuille confirmed this. I continue to actively research this

I notice a trend on the part of PCPers to suspect the value of grids
when used non-psychologically. I gained confidence in Ingrid's
non-personal abilities by doing a grid of airfares between 18 Australian
cities. The result was a map of Australia.


If you need, I can send you my completed reading list.
