Relationship between suprathreshold stimulus auditory brainstem response (ABR) amplitudes and cell density in the medial superior olive (MSO) at 70 dB SPL. Cell density of NADPHd (A–D)-positive cells and parvalbumin (E–H)-positive cells in the MSO as a function of peak II or IV ABR amplitudes using middle- and high-frequency tone stimuli (labeled accordingly) at 70 dB SPL. Few significant correlations were noted (B,D,H), suggesting that ABR responses to suprathreshold stimuli remain fairly constant regardless of the underlying chemical changes.
