Maps of the Student’s t statistic for the (shiverer-control) difference in the tensor eigenvalues shown in Fig. 4. Some white matter tracts such as the anterior part of the anterior commisure (AC, arrowed), external capsule (EC, arrowed) and hippocampal fimbria (F, arrowed) show less significant differences in λ₁ than in λ₂ and λ₃. The lateral cerebellar white matter (C, arrowed), in contrast, shows more significant increases in λ₁ than in λ₂ and λ₃.
