摘要

短期单眼剥夺后观察到的眼优势转移是成年人类视觉稳态可塑性的一种广泛使用的测量方法。双眼竞争和双眼组合技术可以互换使用来表征稳态可塑性,有时会导致矛盾的结果。在这里,我们直接比较了在同一组参与者中,通过双眼竞争或双眼组合测量的短期单眼剥夺对眼睛优势的影响及其对剥夺持续时间(15或120分钟)的依赖性。我们的研究结果表明,双眼竞争和双眼组合都提供了对眼睛优势的可靠估计,这在剥夺前后的技术中都有很强的相关性。此外,与双眼竞争相比,使用双眼组合测量时,15分钟的单目剥夺会导致更大的眼优势转移,但对于这两种技术,眼优势的转移表现出对单目剥夺持续时间的强烈依赖性,更长的剥夺会导致眼优势的更大、更持久的转移。总之,我们的结果表明,双眼竞争和双眼组合都提供了非常一致和可靠的测量优势和短期单眼剥夺的影响。

The duration effect of short-term monocular deprivation measured by binocular rivalry and binocular combination

The ocular dominance shift observed after short-term monocular deprivation is a widely used measure of visual homeostatic plasticity in adult humans. Binocular rivalry and binocular combination techniques are used interchangeably to characterize homeostatic plasticity, sometimes leading to contradictory results. Here we directly compare the effect of short-term monocular deprivation on ocular dominance measured by either binocular rivalry or binocular combination and its dependence on the duration of deprivation (15 or 120 min) in the same group of participants. Our results show that both binocular rivalry and binocular combination provide reliable estimates of ocular dominance, which are strongly correlated across techniques both before and after deprivation. Moreover, while 15 min of monocular deprivation induce a larger shift of ocular dominance when measured using binocular combination compared to binocular rivalry, for both techniques, the shift in ocular dominance exhibits a strong dependence on the duration of monocular deprivation, with longer deprivation inducing a larger and longer-lasting shift in ocular dominance. Taken together, our results indicate that both binocular rivalry and binocular combination offer very consistent and reliable measurements of both ocular dominance and the effect short-term monocular deprivation.

期刊介绍: Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
