  • Title: True checkerboard pattern reversal with light-emitting diodes.
    Author: Epstein CM.
    Journal: Electroencephalogr Clin Neurophysiol; 1979 Nov; 47(5):611-3. PubMed ID: 91489.
    Abstract:
    The use of rectangular red light-emitting diodes permits construction of a true checkerboard pattern-reversal stimulator, which given evoked responses comparable in amplitude and wave form to those obtainable by a TV pattern generator. The device interfaces easily with commercial avergers and allows the incorporation of several features that may increase the sensitivity of visual evoked responses in screening for multiple sclerosis.
