Figure 1.
Morphology of ET cells. A–G, Neurolucida drawings of typical ET cells. The highly branched tufted dendrites ramify throughout a large portion of a single glomerulus, whereas the axons course toward the EPL. Thin lines above and below the GL in this and subsequent figures indicate boundaries of the GL with the olfactory nerve layer (ONL) and EPL, respectively. Scale bar (in G): A–G, 100 μm. The two photographs in G show typical spines (arrows) on the dendrites of the same ET cell.
