“…In either scenario, a brief deprivation duration would still tap on shared mechanisms, though it is noteworthy that the degree of similarity is dependent on other determinants such as the type of visual property examined, assessment task, and stimulus content. This is because experience-dependent plasticity in binocular vision involves a multitude of possible processes 61 and variations in these determinants may tap different neural correlates that perform differently at different time scales 62 , 63 .…”

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.

“…Following previous work (Teyler et al, 2005), our rapid monocular stimulation protocol was designed to minimize adaptation effects by providing a period of eye closure directly after the rapid visual stimulation that was the same duration as the rapid visual stimulation itself (2 min). Generally, a period of adaptation lasts as long as the stimulation (Greenlee et al, 1991; see Başgöze et al, 2018 for an in-depth review). However, it is still possible that adaptation played a role in our results.…”

Long-term potentiation (LTP) is the process of strengthening synaptic efficacy through repeated activation. This fundamental mechanism of neuroplasticity involves a cascade of cellular and molecular changes and underpins the processes of learning and memory formation (Bliss & Collingridge, 1993; Bliss & Lomo, 1973). Early research revealed that the rapid electrical stimulation of presynaptic cells within the rabbit hippocampus induced a lasting increase in the response amplitude of postsynaptic cells (Bliss & Lomo, 1973). Subsequent studies demonstrated similar effects (Bröcher et al., 1992) and characterized the neurochemical changes that occurred as a result of the stimulation (Hayashi et al., 2000; Teyler & DiScenna, 1987). These changes included a rise in postsynaptic calcium, the release of glutamate, and the activation of N-methyld-aspartate (NMDA) receptors (Malenka & Nicoll, 1999). While LTP is typically induced using electrical stimulation in vitro, similar effects (a strengthening of neural responses following stimulation) have been reported in the visual

“…Lunghi et al (2011) first reported the phenomenon using binocular rivalry (i.e., binocular competition); the change lasted for up to 90 min. Other investigators subsequently confirmed this finding via binocular rivalry or binocular combination (Zhou et al, 2013a,b;Bai et al, 2017;Kim et al, 2017;Başgöze et al, 2018;Ramamurthy and Blaser, 2018). The neural basis of this short-term ocular dominance plasticity is thought to occur in the early visual pathway (Lunghi et al, 2015a,b;Zhou et al, 2015;Chadnova et al, 2017;Binda et al, 2018).…”

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.
