This picture shows a coronal section (at about -1.7 to 2.1 mm from bregma) through the brain of a transgenic mouse expressing an axon-targeted GFP variant under control of the CaM kinase II promoter (transgene design by Kathrin & Dirk, pro-nucleus injection by Irm, mouse bred by Hille, section by Axel, photo by Stefan). The background picture of our website is an inverse B&W version of this image.
