  • Title: Detection of cerebral lateralization of function using EEG alpha-contingent visual stimulation II.
    Author: Goodman D, Mulholland T.
    Journal: Int J Psychophysiol; 1988 Nov; 6(4):255-61. PubMed ID: 3225202.
    Abstract:
    The replicative reliability of durations of alpha-blocking following visual stimulation over different cortical sites was assessed with the method of alpha-contingent stimulation. Fourteen right-handed undergraduates were tested in a randomized factorial design. Words or geometric designs of equal luminance were presented by computer to randomly selected visual half-fields contingent on the occurrence of alpha at one of 4 placements (left and right occipital and left and right temporal). The control (mean/s) of alpha-blocking durations was significantly greater for contralateral visual half-field stimulation compared to ipsilateral visual half-field stimulation. This and other results were interpreted in terms of the concept of replicative reliability of retinal-cortical connections to occipital and temporal lobes and affirm the validity and sensitivity of the method.
