摘要: Fluctuations in perceptual dominance during binocular rivalry exhibit several hallmark characteristics. First, switches are not periodic but, instead, stochastic: perception changes unpredictably. Second, despite being stochastic, average durations of vary dependent on the strength rival stimuli: variations contrast, luminance or spatial frequency produce predictable and, hence, alternation rate. Third, originate locally and spread globally over time, sometimes as traveling waves dominance: transitions spatio-temporal events. This essay 1) reviews recent advances our understanding bases these three characteristics dynamics 2) provides an integrated framework to account for those using cooperative competitive interactions among local neural circuits distributed visual field’s retinotopic map. We close with speculations about how that might incorporate top-down influences dynamics.
