Statistically significant FDR-corrected q values are shown (^* q < 0.05 corresponding to uncorrected ^* p < 3.10 × 10⁻³; unpaired t test) for the anisotropy index (AI) and CD (×10⁻² cell/μm²). AI, anisotropy index; cc, corpus callosum; CD, cell density; ec, external capsule; ic, internal capsule; S1, somatosensory cortex; VPL, ventral posterolateral thalamic nucleus.
