Widespread domoic acid damage in olfactory bulb is localized to granule cells. Left: Photomicrograph of coronal section of olfactory bulb stained by amino cupric silver histochemisty with neutral red counterstain. Black amino cupric silver impregnates soma and dendrites of granule cells and neutral red stains soma, axons, and terminals of mitral cells. Additional magnifications of the field this photomicrograph and labeled subdivisions can be found in Figure S2, Supplementary Information. Right: schematic diagram corresponding to photomicrograph showing silver impregnated (black) granule cells and dendritic contacts on lateral dendrites of mitral cells. Schematic after [32].
