Figures 3.

Comparison of post-mortem tissue and T2-weighted images. Each of these figures contains the following: (a) a T2-weighted structural MRI of the human hippocampus and (b) a section of post-mortem human hippocampus stained with cresyl violet to visualise cell bodies. This section is approximately equivalent to the T2-weighted MRI presented in ‘a’. Salient landmarks referred to in the text are marked on the image. (c) Equivalent slice of post-mortem human hippocampus stained with haematoxylin (Weigert) to visualise white matter. Salient landmarks referred to in the text are marked on the image; ‘b’ and ‘c’ are from ‘The Human Brain’ website http://www.thehumanbrain.info/brain/sections.php. (d) This is the same T2-weighted MRI as presented in ‘a’ but now with salient landmarks referred to in the text marked on the image. (e) This is the same section as presented in ‘b’ but now overlaid with hippocampal subregion masks. (f) This is the same section as presented in ‘c’ but now overlaid with hippocampal subregion masks. (g) This is the same section as presented in ‘a’ and ‘d’ but now overlaid with hippocampal subfield masks. Note that this legend also pertains for Figures 4-15.
