Acoustic Trauma Changes the Parvalbumin-Positive Neurons in Rat Auditory Cortex

Figure 1

Auditory brainstem responses before and after noise exposure. (a, b) Representative ABR waveforms following acoustic trauma in noise-exposed group ((a) right ear; (b) left ear) and control group ((c) right ear; (d) left ear). (e) Group data showing that ABR threshold was elevated in the exposed ear of exposed group, but not in the unexposed ear and both ears of the control group. .
