Hg concentrations in freshwater fish, central to their cultural identity, livelihood and diet, were among the highest ever reported. Between 1972 and 1992, a Canadian government program measured Hg concentrations in routine autopsies from this community. In 2017, Grassy Narrows obtained their community's autopsy reports.

While Hg accumulation in the cerebellum has been documented, the basal ganglia has seldom been an object of interest in the Hg scientific literature.
