Reconstruction of the anterior and hippocampal commissures and quantification of structural volumes. Representative dorsal view of reconstructed fibre tract streamlines via the anterior commissure (A, C) and the hippocampal commissure (E, G) in C57Bl/6 (A, E) and BTBR (C, G) adult mouse brains. Streamlines were overlaid on fractional anisotropy maps. Structural volumes of the anterior commissure (B, D) and the hippocampal commissure (F, H) in C57Bl/6 (B, F) and BTBR (D, H) adult mouse brains derived from anatomical T1-weighted MRI images. Scale bar = 1 mm. ROI = region of interest; HC = hippocampal commissure, AC = anterior commissure.
