Analysis of MEG relating to subjective preference of visual motion stimuli

Abstract

Abstract-The aim of this study is to identify the relationship between subjective preference and the human brain responses to visual motion under changing its period. First, preference judgments using the paired-comparison method for sinusoidal movements of a single circular target in horizontal direction were performed. Then, MEG data were recorded during presentations of the most preferred and the least preferred moving stimuli. From the initial delay range of ACF of the alpha wave, the effective duration (τ τ τ τ e ) was analyzed. Results show that the stimulus with most preferred periods has a greater value of τ τ τ τ e than that with least preferred periods at the occipital area, especially in the left hemisphere.
