Acute and Long-Term Effects of Noise Exposure on the Neuronal Spontaneous Activity in Cochlear Nucleus and Inferior Colliculus Brain Slices
Threshold shift in dB SPL (mean ± S.E.) of the auditory brainstem response (ABR) at different frequencies of noise-exposed mice (acute group: filled squares; 7-day group: open triangles; 14-day group: filled circles). Filled asterisks show significant differences between treatment groups and controls. Open asterisks indicate significant recovery of auditory thresholds between the acute and 7-day group (from ).
