Figure 2.

Sections from the OB. (A) Low magnification picture (scale bar = 1mm) showing the large olfactory ventricle (OV) and the easily recognizable laminar structure of the bulb. Asterisks = missing portions. (B) Nissl (blue)/myelin (black) staining. Superficial at top, the OV at bottom. The characteristic layers of the bulb include the glomerular layer (GLM), with its spherical regions of neuropil, the broad, relatively cell free EPL, compact MCL, and striated GCL. Scale bar = 200 µm. (C, D) Camera lucida drawings of Golgi–Cox stained cells, scale bars = 25 µm. (C) Periglomerular cells, whose dendrites extend into glomeruli (grey) and their somata are found in region between the glomeruli. (D) Large, horizontal cells from the EPL. (E) Granule cells, whose dendritic tufts are located in the EPL and somata in the superficial (left) to deep (right) GCL. The cell body of the left-most granule cell was located deep within the MCL.
