Compared cases were affected by Classical BSE (CB), L-type BSE (LB), and Classical scrapie (CS).

Score a: total for neuroanatomical areas that were scored in every animal.

Score b: total for neuroanatomical areas that were scored in each pair.

Score c: total score for all areas only in those sheep where all areas were actually represented in the tissue sections (see Materials and Methods).
