“…27,58 This intriguing phenomenon is observed when SED was measured with either the BR or binocular phase combination methods. To reveal the characteristics of short-term deprivation, Min et al 33,34 investigated if the boost in SED could be increased (cumulative effect) with longer deprivation duration or repeated deprivations over several days. Interestingly, they found no cumulative effect, which suggested to them that the phenomenon acts in an all-or-none fashion.…”

Eye dominance refers to the preference to use one eye more than the fellow eye to accomplish a task. However, the dominant eye revealed can be task dependent especially when the tasks are as diverse as instructing the observer to sight a target through a ring, or to report which half-image is perceived more of during binocular rivalry stimulation. Conventionally, the former task is said to reveal motor eye dominance while the latter task reveals sensory eye dominance. While the consensus is that the motor and sensory-dominant eye could be different in some observers, the reason for it is still unclear and has not been much researched. This review mainly focuses on advances made in recent studies of sensory eye dominance. It reviews studies conducted to quantify and relate sensory eye dominance to other visual functions, in particular to stereopsis, as well as studies conducted to explore its plasticity. It is recognized that sensory eye dominance in observers with clinically normal vision shares some similarity with amblyopia at least at the behavioral level, in that both exhibit an imbalance of interocular inhibition. Furthermore, sensory eye dominance is probably manifested at multiple sites along the visual pathway, perhaps including the level of ocular dominance columns. But future studies with high-resolution brain imaging approaches are required to confirm this speculation in the human visual system.

“…We have suggested that a GABA-mediated account could have contributed to the surround facilitative effects in Experiment 3. Given this, increasing the duration of deprivation would enhance surround facilitative effects in the immediate post-deprivation period, but in a gradual manner akin to the small DE increase observed in Min et al (i.e., 25% increase in magnitude over a 20-fold increase in deprivation duration) 19 . It is unclear at this point if the maintenance of these surround facilitative effects depends on GABAergic concentration or are supported by longer-term mechanisms that are activated with longer deprivation durations.…”

“…While most studies interested in the effects of short-term monocular deprivation have typically employed hours of monocular deprivation, e.g., 2.5 h 10 , 12 – 17 , two recent studies have shown that the DE can be obtained with shorter deprivation durations. For example, Min et al discovered that the interocular contrast balance ratio on a binocular combination task varies little with deprivation durations, producing only a 25% increase in the DE for a 300-min deprivation period compared to a 15-min deprivation period 19 . Similarly, Kim et al found that 15 min of CFS exposure was capable of producing significant shifts in BR dominance that temporarily strengthened the deprived eye 18 .…”

Brief localised monocular deprivation in adults alters binocular rivalry predominance retinotopically and reduces spatial inhibition

Short-term deprivation (2.5 h) of an eye has been shown to boost its relative ocular dominance in young adults. Here, we show that a much shorter deprivation period (3–6 min) produces a similar paradoxical boost that is retinotopic and reduces spatial inhibition on neighbouring, non-deprived areas. Partial deprivation was conducted in the left hemifield, central vision or in an annular region, later assessed with a binocular rivalry tracking procedure. Post-deprivation, dominance of the deprived eye increased when rivalling images were within the deprived retinotopic region, but not within neighbouring, non-deprived areas where dominance was dependent on the correspondence between the orientation content of the stimuli presented in the deprived and that of the stimuli presented in non-deprived areas. Together, these results accord with other deprivation studies showing V1 activity changes and reduced GABAergic inhibition.

“…Recently, a new form of neural plasticity has been reported in adults. Patching one eye (i.e., monocular patching) for a short period (0.5-5 h) of time increases the contribution of the patched eye in binocular vision (Lunghi et al, 2011;Zhou et al, 2013a,b;Bai et al, 2017;Kim et al, 2017;Min et al, 2018Min et al, , 2019Ramamurthy and Blaser, 2018). The change, which is referred to as short-term ocular dominance plasticity (Lunghi et al, 2015a), is linked to the primary visual cortex (Zhou et al, 2017).…”

Action Video Gaming Does Not Influence Short-Term Ocular Dominance Plasticity in Visually Normal Adults

Action video gaming can promote neural plasticity. Short-term monocular patching drives neural plasticity in the visual system of human adults. For instance, short-term monocular patching of 0.5-5 h briefly enhances the patched eye's contribution in binocular vision (i.e., short-term ocular dominance plasticity). In this study, we investigate whether action video gaming can influence this plasticity in adults with normal vision. We measured participants' eye dominance using a binocular phase combination task before and after 2.5 h of monocular patching. Participants were asked to play action video games, watch action video game movies, or play non-action video games during the period of monocular patching. We found that participants' change of ocular dominance after monocular patching was not significantly different either for playing action video games versus watching action video game movies (Comparison 1) or for playing action video games versus playing non-action video games (Comparison 2). These results suggest that action video gaming does not either boost or eliminate short-term ocular dominance plasticity, and that the neural site for this type of plasticity might be in the early visual pathway.
