Olfactory bulb neuronal degeneration in a female B6C3F1 mouse from a chronic study. The arrow indicates the vacuolation and neuronal degeneration of the olfactory bulb. Gl, glomerular layer; EPl, external plexiform layer; GrO, internal granule cell layer.

Higher magnification of the internal granule cell layer in the normal olfactory bulb in a female B6C3F1 mouse from a chronic study.

Granulovacuolar neuronal degeneration in a male F344/N rat from an acute study. The black arrowhead indicates neuronal granulovacuolar change, the black arrows identify neurons with central chromatolysis, and the white arrow identifies a genuine basophilic necrotic neuron.

Granulovacuolar neuronal degeneration in a male F344/N rat from an acute study. Higher magnification of Figure 4. The black arrow indicates neuronal granulovacuolar change, the arrowhead identifies a neuron with central chromatolysis, and the white arrow identifies a genuine basophilic necrotic neuron.
