Auditory brainstem and middle latency responses in non-human primates.

N Kraus, D I Smith, N L Reed

    Hearing Research
    |March 1, 1985
    PubMed
    Summary

    Auditory brainstem (ABR) and middle latency responses (MLR) were measured in primates. ABR wave latencies mature rapidly, reaching adult values within months, while MLRs show species-specific variations.

    Area of Science:

    • Neuroscience
    • Comparative Psychology
    • Primate Auditory Neuroscience

    Background:

    • Auditory evoked potentials, including Auditory Brainstem Responses (ABR) and Middle Latency Responses (MLR), are crucial for assessing auditory pathway function.
    • Understanding the development and species-specific characteristics of these responses in non-human primates provides insights into human auditory development and evolution.

    Purpose of the Study:

    • To investigate and compare Auditory Brainstem Response (ABR) and Middle Latency Response (MLR) characteristics across different primate species.
    • To examine the developmental trajectory of ABR latencies in young primates.
    • To compare primate auditory evoked potentials with existing data from humans and other vertebrates.

    Main Methods:

    • ABR and MLR were recorded from crab-eating macaques, white-handed gibbons, siamangs, and orangutans.

  • Latency-intensity functions were generated for ABR, and MLR recordings were taken at specific dB levels.
  • Analysis included latency-intensity functions, interwave intervals, thresholds, percent detectability, and MLR characteristics.

    • Main Results:

    • ABR Waves II and IV showed the largest amplitudes and consistent detection across all species at low stimulus intensities.
    • Young macaques (as young as 5 days) exhibited adult-like latencies for ABR Waves I and II, with Waves III and IV maturing by 15 months.
    • A consistent, broad negative MLR was observed in all subjects, with longer latency MLRs showing individual variability but replicability within individuals.

    Conclusions:

    • Primate ABR development is rapid, with adult latencies achieved within the first year of life.
    • MLR components demonstrate both conserved features and species-specific variations across primates.
    • These findings contribute to a comparative understanding of auditory system maturation and function in primates.
