. The brain of the tiger salamander, Ambystoma tigrinum. Brain; Ambystoma. ILLUSTRATIONS 385 Figure 109.—An obliquely longitudinal section through the ventrolateral border of the adult hemisphere ('42, fig. 16). (lolgi method. X 80. The section is inclined to the sagittal plane, with the anterior and dorsal sides much more lateral. It cuts the accessory olfactory bulb and the anterior end of the caudate nucleus, whose gray {nucxaud.) is unimpregnated. Above and externally of this is a dense impregnation of the caudate neuropil with sharply defined borders. Some unimpregnated cell bodies are enmeshed within this neuropil, only the axonic component of which is impregnated. This neuropil is continuous with that of the remainder of the striatal complex shown in figure 108. Anteriorly of it, six neurons of the an- terior olfactory nucleus are impregnated. Figure llOA, B.—Diagrams of the structure of the olfactory bulb as seen in horizontal section of the adult brain. A.—The outline is taken from a section at the widest part of the olfactory bulb and the elements are drawn to scale from several Golgi sections, most of them from the same specimen ('246, fig. 1). X 50. Glomeruli are outlined with dotted lines. The approximate locus of figure hob' is indicated. The following types of neurons have been described: (1) periglomeridar cells; (2) mitral cells; (3) subglomerular tufted cells; (4) granule cells; (5) cells intermediate between granules and neurons of nucleus olfactorius anterior; (6) transitional cells of nucleus olfactorius anterior. layers of the olfactory bulb as seen in horizontal section after fixation in formalin- Zenker followed by Mallory's stain ('246, fig. 4).
