  • Title: Comparison of two types of visual evoked potentials: pattern reversal and eye movement (lambda).
    Author: Scott DF, Moffett A, Bickford RG.
    Journal: Electroencephalogr Clin Neurophysiol; 1981 Jul; 52(1):102-4. PubMed ID: 6166448.
    Abstract:
    The averaged visual evoked potentials of 10 normal subjects were studied either with eyes fixated while a chequerboard reversed or when they moved their eyes across the stationary chequerboard. The resulting occipital potentials averaged using a computer of averaged transients were discrepant for the 2 conditions. The latency of the P100 component was similar allowing for the difference in latency in the computer triggering system but the resulting wave forms were different. There was a prominent negative component preceding the P100 in the lambda response and a prominent negative component following the P100 for the pattern shift. The possible reasons for the findings are discussed.
