Abstract:

Standard neuroanatomical atlases have several drawbacks as learning tools. They consist of pages of photographed brain slices with numbered leader lines and a list of names correlated with the numbers.  Since the individual structures in the nervous system blend together, the student has trouble distinguishing their borders. Furthermore, the three-dimensional form of buried structures is difficult to grasp and little information on function is provided. As a result, the student expends considerable energy finding information that is of limited value.  

 

Our solution was to create an interactive atlas that facilitates the identification of structures and provides information on their functions. As the cursor moves over the image, each structure is outlined, its name appears in a nearby text box, and its function is described in both text and audio form. A "Vascular Territories" option overlies each image with color-coded interactive bitmap. This feature facilitates understanding of stroke syndromes.  A "Self Quiz" option tests the student's knowledge, calculates a score, and provides correct answers when necessary. The database consists of MR images in three planes and different imaging modalities, representative brainstem and spinal cord sections, angiograms, illustrations, animations of pathways and 3-dimensional, rotating models. The user can view brainstem and spinal cord slices in either the pathological orientation (dorsal side up) or the radiological orientation (dorsal side down). A small neuroimaging manual and an illustrated glossary are also provided. Students are given individual copies of the program on CD and it is available on the University of Toronto server.

 

Benefit in Attending Session:

We will show how an interactive program can be used to supplement or replace laboratories in human brain dissection.
