Sagittal sections of interest in adult mice (16 wk of age). (A) Representative image of histological workflow and specific lateral positions at which sagittal sections were cut for quantitative analysis. (B) Regions quantified using ImageJ have been traced on the representative image of the sagittal section 7 of interest lateral 0.72 mm. (C) Representative image of sagittal section 8 of interest (lateral 1.32 mm). (D) Representative image of sagittal section 9 of interest (lateral 2.52 mm). All brain sections were stained using cresyl violet and luxol blue. 4V, fourth ventricle; 7N, facial nucleus; aca, anterior part of anterior commissure; acp, posterior part of anterior commissure; AD, anterodorsal thalamic nucleus; B, bottom; cc, corpus callosum; Cg, cingulate cortex; Cpu, caudate putamen; DG, dentate gyrus; DS, dorsal subiculum; f, fornix; fi, fimbria; Folia, number of folia; fp, fibre of pons; Gn, geniculate nucleus; GP, globus pallidus; hif, hippocampal fissure; HP, hippocampus; ic, internal capsule; IGL, internal granular layer of cerebellum; InfC, inferior colliculus; Lat, lateral cerebellar nucleus; LR4V, fourth ventricle; LSV, ventral part of lateral septal nucleus; LV, lateral ventricle; M1, primary motor cortex; M2, secondary motor cortex; Med, medial cerebellar nucleus; Mn, mammilary nucleus; Mol, molecular layer of HP; och, optic chiasm; opt, optic tract; Or, oriens layer of HP; Pir, piriform cortex; Pn, pontine nuclei; Rad, radiatum layer of HP; S1, primary somatosensory cortex; sm, stria medullaris; SN substantia nigra; SNR, substantia nigra region; T, top; TB_Height1, height at Bregma +0.86 mm; TB_Height2, height at Bregma −1.34 mm; TB_Width, width of the total brain; TBA, total brain area; TCA, total cerebellar area; TILpy, total internal length of pyramidal cell layer of HP; TOL, total outer length.
