Chronic Lead Exposure Results in Auditory Deficits and Disruption of Hair Cells in Postweaning Rats

Figure 3

Effects of developmental lead exposure on the ultramicrostructure of spiral ganglion neurons. Spiral ganglion neurons in the control group had a round surface with a smooth cell membrane. Spiral ganglion neurons in lead-exposed rats showed a recessed membrane and loose cytoplasm with autophagosomes, indicating degenerative changes.
