“…In these studies researchers have applied anodal tDCS to the left prefrontal cortex with the consistent finding that stimulation improved verbal WM performance using 2-and 3-back WM tasks (Fregni et al, 2005a;Ohn et al, 2008;Andrews et al, 2011;Mulquiney et al, 2011;Zaehle et al, 2011). These results also showed that cathodal stimulation of the left prefrontal cortex did not improve accuracy on the task.…”

“…During cathodal and anodal stimulation 1.5 mA current was applied for 10 min. Previous studies have found an effect of tDCS with 10 min of stimulation (Furubayashi et al, 2008;Berryhill et al, 2010;Andrews et al, 2011;Mulquiney et al, 2011;Antal et al, 2012;Berryhill and Jones, 2012;Kasashima et al, 2012). During sham stimulation participants received stimulation in which current lasted for 20 s at the start and end of the 10 min but no stimulation occurred in between.…”

The nature of parietal contributions to working memory (WM) remain poorly understood but of considerable interest. We previously reported that posterior parietal damage selectively impaired WM probed by recognition (Berryhill and Olson, 2008a). Recent studies provided support using a neuromodulatory technique, transcranial direct current stimulation (tDCS) applied to the right parietal cortex (P4). These studies confirmed parietal involvement in WM because parietal tDCS altered WM performance: anodal current tDCS improved performance in a change detection task, and cathodal current tDCS impaired performance on a sequential presentation task. Here, we tested whether these complementary results were due to different degrees of parietal involvement as a function of WM task demands, WM task difficulty, and/or participants' WM capacity. In Experiment 1, we applied cathodal and anodal tDCS to the right parietal cortex and tested participants on both previously used WM tasks. We observed an interaction between tDCS (anodal, cathodal), WM task difficulty, and participants' WM capacity. When the WM task was difficult, parietal stimulation (anodal or cathodal) improved WM performance selectively in participants with high WM capacity. In the low WM capacity group, parietal stimulation (anodal or cathodal) impaired WM performance. These nearly equal and opposite effects were only observed when the WM task was challenging, as in the change detection task. Experiment 2 probed the interplay of WM task difficulty and WM capacity in a parametric manner by varying set size in the WM change detection task. Here, the effect of parietal stimulation (anodal or cathodal) on the high WM capacity group followed a linear function as WM task difficulty increased with set size. The low WM capacity participants were largely unaffected by tDCS. These findings provide evidence that parietal involvement in WM performance depends on both WM capacity and WM task demands. We discuss these findings in terms of alternative WM strategies employed by low and high WM capacity individuals. We speculate that low WM capacity individuals do not recruit the posterior parietal lobe for WM tasks as efficiently as high WM capacity individuals. Consequently, tDCS provides greater benefit to individuals with high WM capacity.

“…Studies suggest that the global effect induced by NIBS is dependent on several factors including electrode placement (Sehm et al, 2013), connectedness of the targeted brain region to other regions (e.g., Rounis et al, 2006vs. Cocchi et al, 2015, and whether the participant is concurrently undertaking a task (Nitsche et al, 2003;Fregni et al, 2005;Hummel et al, 2005;Kujirai et al, 2006;Andrews et al, 2011). This interplay between brain connectivity and NIBS in health and disease has been the focus of many recent studies.…”

“…tDCS has been shown to successfully improve various perceptual or cognitive abilities both in healthy participants and in patients, and when administered either with (Looi, Duta, Brem, Huber, Nuerk & Cohen Kadosh, 2016) or without a concurrent training (Coffman, Clark & Parasuraman, 2014). In particular, tDCS has been found to improve functions such as working memory (Andrews, Hoy, Enticott, Daskalakis & Fitzgerald, 2011;Fregni, Boggio, Nitsche, Bermpohl, Antal, Feredoes, Marcolin, Rigonatti, Silva, Paulus & Pascual-Leone, 2005), long-term memory (Marshall, Molle, Hallschmid & Born, 2004;Sandrini, Brambilla, Manenti, Rosini, Cohen & Cotelli, 2014), language (Fertonani, Rosini, Cotelli, Rossini & Miniussi, 2010;Fiori, Coccia, Marinelli, Vecchi, Bonifazi, Ceravolo, Provinciali, Tomaiuolo & Marangolo, 2010;Monti, Cogiamanian, Marceglia, Ferrucci, Mrakic-Sposta, Vergari, Zago & Priori, 2008;Pisoni, Papagno & Cattaneo, 2012;Ross, McCoy, Wolk, Coslett & Olson, 2010;Sparing, Dafotakis, Meister, Thirugnanasambandam & Fink, 2008), visual and attentional skills (Antal, Nitsche, Kruse, Kincses, Hoffmann & Paulus, 2004;Bolognini, Fregni, Casati, Olgiati & Vallar, 2010;Kraft, Roehmel, Olma, Schmidt, Irlbacher & Brandt, 2010;Ding, Li, Spiegel, Chen, Chan, Luo, Yuan, Deng, Yu & Thompson, 2010). However, efficacy of tDCS has recently been disputed (e.g.…”

The application of online transcranial random noise stimulation and perceptual learning in the improvement of visual functions in mild myopia

It has recently been demonstrated how perceptual learning, that is an improvement in a sensory/perceptual task upon practice, can be boosted by concurrent high-frequency transcranial random noise stimulation (tRNS). It has also been shown that perceptual learning can generalize and produce an improvement of visual functions in participants with mild refractive defects.By using three different groups of participants (single-blind study), we tested the efficacy of a short training (8 sessions) using a single Gabor contrast-detection task with concurrent hftRNS in comparison with the same training with sham stimulation or hf-tRNS with no concurrent training, in improving visual acuity (VA) and contrast sensitivity (CS) of individuals with uncorrected mild myopia.A short training with a contrast detection task is able to improve VA and CS only if coupled with hf-tRNS, whereas no effect on VA and marginal effects on CS are seen with the sole administration of hf-tRNS.Our results support the idea that, by boosting the rate of perceptual learning via the modulation of neuronal plasticity, hf-tRNS can be successfully used to reduce the duration of the perceptual training and/or to increase its efficacy in producing perceptual learning and generalization to improved VA and CS in individuals with uncorrected mild myopia.
