“…Previously, the applicability and usefulness of such extra-intra measurements and calculations were demonstrated in the field of equine craniometry [7] with special emphasis on the so-called Indirect Distances in a three-dimensional Coordinate System. Data from numerous equine craniometric studies [7,10,18,19,22,25,26], various imaging procedures [2; 12, 16, 32, 33] and some electrophysiological approaches [1,3,6] are currently available. However, they appear limited in their methodical scope because a topographical link is missing between the two subjects of interest, i.e.…”
