    Modulation of the cognitive event-related potential P3 by transcranial direct current stimulation: Systematic review and meta-analysis
    2022-01 - Mendes, Augusto J.; Pacheco-Barrios, Kevin; Lema, Alberto; Gonçalves, Óscar F.; Fregni, Felipe; Carvalho, Sandra; Leite, Jorge
    Transcranial direct current stimulation (tDCS) has been widely used to modulate cognition and behavior. However, only a few studies have been probing the brain mechanism underlying the effects of tDCS on cognitive processing, especially throughout electrophysiological markers, such as the P3. This meta-analysis assessed the effects of tDCS in P3 amplitude and latency during an oddball, n-back, and Go/No-Go tasks, as well as during emotional processing. A total of 36 studies were identified, but only 23 were included in the quantitative analysis. The results show that the parietal P3 amplitude increased during oddball and n-back tasks, mostly after anodal stimulation over the left dorsolateral prefrontal cortex (p = 0.018, SMD = 0.4) and right inferior frontal gyrus (p < 0.001, SMD = 0.669) respectively. These findings suggest the potential usefulness of the parietal P3 ERP as a marker of tDCS-induced effects during task performance. Nonetheless, this study had a low number of studies and the presence of considerable risk of bias, highlighting issues to be addressed in the future.

    The effects of direct current stimulation and random noise stimulation on attention networks
    2021-03-18 - Lema, Alberto; Carvalho, Sandra; Fregni, Felipe; Gonçalves, Óscar F.; Leite, Jorge
    Attention is a complex cognitive process that selects specific stimuli for further processing. Previous research suggested the existence of three attentional networks: alerting, orienting and executive. However, one important topic is how to enhance the efficiency of attentional networks. In this context, understanding how this system behaves under two different modulatory conditions, namely transcranial direct current stimulation (tDCS) and transcranial Random Noise Stimulation (tRNS), will provide important insights towards the understanding of the attention network system. Twenty-seven healthy students took part on a randomized single-blinded crossover study, testing the effects that involved three modalities of unilateral stimulation (tRNS, anodal tDCS, and sham) over the DLPFC, during the performance of the attention network test (ANT) in three different conditions: standard, speed and accuracy. Results showed that tRNS was able to increase attention during more complex situations, namely by increasing alerting and decreasing conflict effect in the executive network. Under the Speed condition, tRNS increased efficiency of the alerting network, as well as under the more demanding conflict network, tRNS overall increased the performance when comparing to sham. No statistical significant effects of tDCS were observed. These results are compatible with the attention requiring the synchronization of pre-existing networks, rather the reinforcement or creation of new pathways.

    Mind wandering: Tracking perceptual decoupling, mental improvisation, and mental navigation
    2020-10-15 - Gonçalves, Óscar F.; Silva, Mariana Rachel Dias da; Carvalho, Sandra; Coelho, Patrícia; Lema, Alberto; Mendes, Augusto J.; Branco, Diogo; Collus, Jorge; Boggio, Paulo S.; Leite, Jorge
    Background: Mind wandering is a prevalent phenomenon. However, the concept of mind wandering is associated with distinct and often orthogonal concepts, and research- ers are still debating the best strategies to gain access to mind-wandering processes. Nonetheless, there is a progressive acknowledgment that mind wandering is a multi- dimensional and heterogeneous construct. We argue that to fully understand mind wandering, we need to look at dimensions assessing the process (i.e., perceptual decoupling), dynamics (i.e., mental improvisation), and content (i.e., mental naviga- tion). Objective: The objective of this study was to develop a self-report measure of mind wandering—the Mind Wandering Inventory (MWI)—to capture the heterogene- ity of mind wandering in terms of process, dynamic, and content components. Method: Five language versions of the MWI were administered to an international sample of 1,162 individuals. Results: Results showed that the MWI had good levels of internal consistency. In terms of internal structure, we found a first factor to index perceptual decoupling, a second to index mental improvisation, and a third to index mental navigation. Additionally, a study of concurrent validity with Spontaneous and Delib- erate Mind Wandering scales suggested that MWI has significant correlations with previous mind-wandering scales and that factors 1 (perceptual decoupling) and 2 (mental improvisation) seemed to be more closely associated with spontaneous than deliberate mind wandering. Finally, individuals coming from sciences major back- ground reported increased levels of mind wandering when compared with participants from both health, social and human sciences background.
