High-resolution radiographs of CNS. (a) Overall radiograph taken by projection-CT geometry using 12 keV X-rays. The areas indicated by the circle and rectangle were further radiographed with an objective lens using 7.13 keV X-rays; high-resolution images are shown in (b) and (c). (b) Radiograph of supraesophageal ganglion showing neurons forming elaborate networks. (c) Radiograph of ventral nerve cord showing neurons located near connective axons. Transmittances are shown in grayscale. Scale bars: 5 µm. |
