ABSTRACT

In order to present the optimal neuroscience tutorial material for medical students and researchers,this study is aimed to make neuro-digital slide and neuro-atlas based on the histological specimens of human spinal cord and brain stem. Cadavers which had agreed for organ donation for research purpose were used in this study. Brains and spinal cords were extracted within 24 hours after death, and then fixed with 10% neutral buffered formalin. Paraffin blocks were made with the following regions; 8 regions from the spinal cord (the levels of the upper cervical segment, the cervical enlargement, the upper thoracic segment, the mid thoracic segment, the lower thoracic segment, the upper lumbar segment, the lumbar enlargement, the sacral segment), 14 regions from the brain stem (the levels of the spinomedullary junction, the pyramidal decussation, the medial lemniscus decussation, the obex,the mid-olivary medulla, the upper medulla, the pontomedullary junction, the lower pons, the mid pons, the upper pons, the isthmus rhombencephali, the inferior colliculus, the superior colliculus, the posterior commissure). Using virtual microscope software, we made digital neuro-slides which can be used anywhere and anytime regardless of equipment of microscope. To help understanding anatomy and functions of nervous tissue, we also made neuro-atlas based on the digital slide images. As results, the outline and detailed structures of nuclei and tracts are easily discriminated and also matched with marks and nomenclatures of neuro-atlas. Moreover, the cytoarchitecture of each nucleus and histological features can be well distinguished. We hope that this product would be used as a useful neuroscience tutorial material for the medical and paramedical school students, clinical trainees like interns and residents, and also neuroscience researchers.
