Well, Hello!  Nice of you to meander in.  You are looking at an image of a sagittal section of the mouse brain.  It has been Nissel stained, placed on a glass slide and a glass coversheet has been placed on it.   It is the primary image.  The next image is the same sagittal section of the mouse brain - however, this one has labels.  Finally here is the sketch of the sagittal section.
