    This study introduces a microcomputer-controlled system for binaural measurements, analyzing neuronal responses to auditory stimuli. It enables detailed investigation of auditory processing and binaural interactions.

    Area of Science:

    • Neuroscience
    • Bioengineering
    • Auditory Neuroscience

    Background:

    • Binaural hearing involves processing auditory information from both ears.
    • Accurate measurement of neuronal responses is crucial for understanding auditory perception.
    • Existing methods may lack the flexibility for detailed binaural analysis.

    Purpose of the Study:

    • To develop and validate a novel microcomputer-controlled system for binaural auditory measurements.
    • To investigate the effects of varying auditory stimuli parameters on neuronal activity.
    • To provide a versatile tool for steady-state and transient binaural research.

    Main Methods:

    • A microcomputer controls a dual-channel sine-wave generator for auditory stimulation.
    • On-line measurement of neuronal spike counts from experimental subjects.
