  • Title: N1 latency following acute pure-tone trauma.
    Author: Sikora MA, Morizono T.
    Journal: Hear Res; 1983 Jul; 11(1):93-101. PubMed ID: 6885650.
    Abstract:
    The latency of the N1 component of tone burst evoked compound action potentials was examined in chinchilla following acute pure-tone trauma. At and below the trauma frequency (4 kHz) the N1 latency at threshold generally increased, while above the trauma frequency it decreased; tonotopically paralleling pitch shifts observed in humans following pure-tone trauma. When N1 latency at threshold is considered across animals as a linear function of dB SPL at threshold, after trauma a high degree of linear correlation was found at 6 and 8 kHz, while a low degree of linear correlation was found at 4 kHz. An interpretation and the significance of the data are discussed.
