    Summary

    Evoked potentials, including visual, brainstem, and somatosensory, offer objective electrophysiological insights. These non-invasive tests aid in diagnosing neurological conditions like multiple sclerosis and evaluating sensory function.

    Area of Science:

    • Neuroscience
    • Electrophysiology

    Background:

    • Electrophysiological studies have advanced with techniques like signal averaging.
    • Low-amplitude neural potentials can now be recorded in response to stimuli.

    Purpose of the Study:

    • To highlight the diagnostic utility of evoked potentials.
    • To detail the applications of visual, brainstem, and somatosensory evoked potentials.

    Main Methods:

    • Utilizing signal averaging to record low-amplitude electrical potentials.
    • Analyzing latency prolongations as indicators of clinical abnormalities.

    Main Results:

    • Evoked potentials provide objective evidence for subclinical neurological diseases.
    • Latency prolongations in evoked potentials signify clinical abnormalities.

    Conclusions:

    • Evoked potentials are valuable, non-invasive electrodiagnostic tools.
    • These tests are crucial for diagnosing multiple sclerosis and other neurological disorders.
    • Applications extend to neonatal evaluations, tumor diagnosis, surgical monitoring, and coma differentiation.
