While searching for a movement notation reference I was amused to discover my name in a bulletin board discussion on the dynamosphere. Most of the little I wrote on this and about notation after my 1983 doctorate has appeared in the Laban Guild magazine (for example no. 27.1 08 cites several articles). A useful teaching/ study tool for space was Visual Choreutics, a set of maps, and if your library doesn't have this I could send a copy.
Re the dynamosphere some coincidences were interesting (Hampshire's theory of mind), and the new scanning devices that reveal brain activity so well may perhaps encourage a more spatial understanding of the mental field.
My current movement writings relate to expression, psychotherapy and speech - no key links to notation, though it provides a convenient jotting device.
