Figure 1From: Tonotopic reorganization and spontaneous firing in inferior colliculus during both short and long recovery periods after noise overexposureABR Thresholds of auditory brainstem response before and after noise exposure (NE). Statistical data representative of ABR (auditory brainstem response) thresholds before and one day after noise exposure (n = 13 from 13 animals) in guinea pigs. Four frequencies were tested: 2 kHz, 4 kHz, 8 kHz, and 16 kHz. *Significant difference from pre-NE group at the same frequency (P < 0.01).Back to article page
