TABLE 1. Distribution of mutant Htt aggregates at 6 months.

Diffuse nuclear or neuropil aggregate levels were scored from (-) absent, (tr) trace, to (+, ++, +++, or ++++) for increasing abundance. (High) and (Low) indicate representative animals with relatively high or low aggregate density representing the variability between animals of the same sex.
