Gross sections (GSs), white matter (WM), grey matter (GM), dorsal horn (DH), ventral horn (VH), central canal (CC). *Segment volumes calculated using Archimedes’ principle after segmentation. Other volumetric measurements were obtained using the Cavalieri’s principle. Coefficient of error mean (mean CE) was calculated according to Sahin and Ergur (2006) [26].
