Imagine moving to a new city and, prior to the move, you study maps of the area to acquaint yourself with the surroundings. The maps you consult are oriented toward the south. When you arrive in the new city and begin to travel through the local area, the maps provided by the local government are oriented toward the north.Imagine how confusing this would be-especially when navigating one-way streets and determining the relationships between nearby landmarks. This is how neuroanatomy has been taught for more than 20 years. Prior to the development of computed tomography (CT) and magnetic resonance imaging (MRI), the standard neuroanatomical cross-sectional orientation was with the posterior (dorsal) aspects of the spinal cord at the top of the field and the anterior (ventral) aspects at the bottom of the field (Figure 1A). There is no established reason for this historical orientation, but presumably it arose from the embryologic orientation with the ventral surface of the embryo oriented at the bottom of the field and the dorsal surface of the embryo at the top of the field. When the cross-sectional imaging techniques were developed, the standard view adopted by the developers and clinicians was with posterior at the bottom of the field and anterior at the top of the field (180 degrees different than the neuroanatomical orientation) (Figure 1B). This orientation was established because this was the position of the patient in the scanner-supine with an inferior view (Hendee, 1989).Haines and his colleagues recognized this conflict 20 years ago and they suggested that neuroanatomists adjust their teaching to this new clinical orientation to avoid confusion and to keep all crosssectional views in the same orientation (Haines et al., 2002). In subsequent years, a few neuroanatomical atlases were published with both orientations, but the field as a whole did not make this transition. This has led students to being taught cross-sectional neuroanatomy in one orientation and then switching that orientation when they examine CT or MRI images. As an aside, the anatomical community made this change as CT and MRI became more commonly used and most anatomical textbooks and atlases now use the standard
