Figure 13. Thick (80 μm) sections of Golgi-Kopsch preparations of the prosoma of sixth instar Phidippus johnsoni. 1, Parasagittal section. 2,4, Horizontal sections. 3, Sagittal (midline) section. Golgi-Kopsch preparations can selectively stain nerve fibers, but it is not possible to determine just what fibers will be stained, and the results can be misleading. Here some of the major fiber tracts in the subesophageal part of the CNS have been stained.
