    Surface-recorded visual evoked potentials (VEPs) were investigated using flash stimuli. This study identified specific neural generators within the visual pathway, offering a new method for lesion localization.

    Area of Science:

    • Neuroscience
    • Ophthalmology
    • Biomedical Engineering

    Background:

    • Surface-recorded visual evoked potentials (VEPs) from subcortical neural elements are poorly described.
    • Existing literature on visual potentials shows considerable disagreement.

    Purpose of the Study:

    • To characterize surface-recorded VEPs generated by subcortical visual pathways using flash stimuli.
    • To investigate the origins and generators of these potentials.
    • To assess their utility in defining lesion sites along the visual pathway.

    Main Methods:

    • Flash stimuli were used to evoke potentials recorded from multiple scalp locations with a non-cephalic reference.
    • Potentials were amplified within a specific frequency band to isolate neural activity.
    • Effects of eye position and stimulus intensity were analyzed in 9 subjects.

    Main Results:

    • A series of VEP components within 100 ms of photic stimulation were identified as volume-conducted activity.
    • Early components (first 4-5) appear to originate in the retina.
    • Later components suggest generation in the optic nerve/tracts and potentially thalamo-cortical pathways.

    Conclusions:

    • Surface-recorded VEPs provide insights into subcortical visual pathway activity.
    • These potentials may complement pattern VEPs for precise lesion localization.
    • The study clarifies generators of VEPs activated by luminosity changes.
