The morphology and intercellular relations of cells in the matrix, lower intermediate, and upper intermediate laminae of the cerebral hemisphere of rabbit embryos was studied with the electron microscope. Models of cells reconstructed from serial sections confirm previous observations made with the Golgi technique. Most cells in the matrix lamina appear to(More)
Plastic (araldite) needles were implanted in the cerebral cortex in order to evaluate changes produced by an indwelling and relatively inert foreign body. The implants were removed together with surrounding cortex after 4-723 days and the implant-CNS boundary analyzed by light and electron microscopy. Three border conditions were observed at the surface of(More)
Histopathological changes of the cerebral cortex in response to small, penetrating metal and non-metal implants were analyzed by means of light and electron microscopy. The needle-shaped implants were left in place during all stages of histological preparation and embedded in plastic together with the cortex. Changes of the brain-implant boundary were(More)
At many medical schools, the medical library assists faculty in finding and integrating new technology into the classroom, student laboratories, and lecture or small group sessions. Libraries also provide faculty with a place to do development. This paper recounts the author's experience creating software-based educational materials. In the process of(More)
Three types of glial cells can be recognized on the basis of their form, the size and shape of the nucleus, and distinctive cytoplasmic characteristics when reconstructed from serial electron micrographs of the toad spinal cord. They correspond to astrocytic neuroglial cells, oligodendrocytes, and microgliacytes described with the light microscope.(More)
Four classes of glial cells can be recognized in the central nervous system of turtles and birds on the basis of nuclear characteristics (methylene blue) and external morphology (Golgi technique). It seems likely that astrocytes and ependymal cells have a similar origin and function, but no evidence has been seen to indicate that transitional forms exist(More)
