“…Such structural changes can be examined via cortical thickness and shape and/or volumetric changes in grey matter in cortical and subcortical regions involved in language learning, processing, and control as well as in changes in the diffusivity of white matter tracts connecting these regions. Much of the evidence on neuroplasticity and structural changes associated with L2 learning in adults comes from training studies and longitudinal studies (for reviews, see DeLuca et al, 2019;Li et al, 2014; for review of transcranial stimulation techniques applied to enhance L2 learning, see Balboa-Bandeira et al, 2021). As reviewed by Li et al (2014), structural changes in the brain are mirrored by functional neural patterns shown in fMRI studies.…”

The past decades have seen an explosion of research using electrophysiological or neuroimaging techniques for studying the neurocognitive underpinnings of second language (L2) processing. Although this field has a shorter history than does research on language learning more generally, important insights into the neurocognitive basis of L2 processing have driven it to the center stage of language science. In this target article for Language Learning’s 75th Jubilee volume, I illustrate the field's impressive achievements by selectively reviewing electrophysiological and neuroimaging research on L2 processing and bilingual brain organization. I also review changing perspectives in the field (including individual difference and experience‐based perspectives, neural network approaches, neuroplasticity, and L2‐learning related neural changes) and identified challenges, promises, and future directions (revisit native‐speaker benchmark, increase linguistic diversity, enhance ecological validity, intensify research on child L2 learners’ brain, adopt lifelong approach to L2 learning) that can lead to a better understanding of the neural underpinnings of L2 learning and processing.

“…This allows researchers to promote or inhibit local neuronal activation, to effectively simulate cortical lesions and modulate brain activity painlessly (Nitsche and Paulus, 2000 , 2001 ; Woods et al, 2016 ; Fertonani and Miniussi, 2017 ). The sheer increase in publications observed in the last decade makes it clear that NIBS techniques have been established as valuable tools to study language (Flöel et al, 2008 ; Nitsche et al, 2008 ; Fiori et al, 2011 ; Jacobson et al, 2012 ; Monti et al, 2013 ; Rufener et al, 2017 , 2019 ; Zoefel and Davis, 2017 ; Balboa-Bandeira et al, 2021 ; Sun et al, 2022b ) and language disorders such as aphasia (Torres et al, 2013 ; Turkeltaub, 2015 ; Meinzer et al, 2016 ) and stuttering (Thiel et al, 2006 ; Chesters et al, 2018 ; Busan et al, 2019 ; Karsan et al, 2022 ).…”

IntroductionLanguage production is a finely regulated process, with many aspects which still elude comprehension. From a motor perspective, speech involves over a hundred different muscles functioning in coordination. As science and technology evolve, new approaches are used to study speech production and treat its disorders, and there is growing interest in the use of non-invasive modulation by means of transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS).MethodsHere we analyzed data obtained from Scopus (Elsevier) using VOSViewer to provide an overview of bibliographic mapping of citation, co-occurrence of keywords, co-citation and bibliographic coupling of non-invasive brain stimulation (NIBS) use in speech research.ResultsIn total, 253 documents were found, being 55% from only three countries (USA, Germany and Italy), with emerging economies such as Brazil and China becoming relevant in this topic recently. Most documents were published in this last decade, with 2022 being the most productive yet, showing brain stimulation has untapped potential for the speech research field.DiscussionKeyword analysis indicates a move away from basic research on the motor control in healthy speech, toward clinical applications such as stuttering and aphasia treatment. We also observe a recent trend in cerebellar modulation for clinical treatment. Finally, we discuss how NIBS have established over the years and gained prominence as tools in speech therapy and research, and highlight potential methodological possibilities for future research.

“…Because of its potential to induce long‐lasting modulations of cortical excitability, tDCS has been used to investigate cognitive functions (Bestmann et al, 2015; Farhat et al, 2022) such as language (Balboa‐Bandeira et al, 2021), memory (Galli et al, 2019), perception (Lavezzi et al, 2022) and executive function (de Boer et al, 2021). In these studies, the cognitive effects of tDCS are believed to occur through the modulation of membrane excitability leading to a cascade of neurophysiological events culminating in observable modifications of behaviour (Bestmann et al, 2015).…”

Transcranial direct current stimulation (tDCS) is a non‐invasive brain stimulation technique that can modulate brain activity through the application of low‐intensity electrical currents. Based on its reported effects on corticospinal excitability (CSE), tDCS has been used to study cognition in healthy individuals and reduce symptoms in a variety of clinical conditions. Despite its increasing popularity as a research and clinical tool, high interindividual variability has been reported in the response to protocols using transcranial magnetic stimulation (TMS) to assess tDCS‐induced changes in CSE leading to several nonsignificant findings. In this systematic review, studies that reported no significant modulation of CSE following tDCS were identified from PubMed and Embase (Ovid) databases. Forty‐three articles were identified where demographic, TMS and tDCS parameters were extracted. Overall, stimulation parameters, CSE measurements and participant characteristics were similar to those described in studies reporting positive results and were likewise heterogeneous between studies. Small sample sizes and inadequate blinding were notable features of the reviewed studies. This systematic review suggests that studies reporting nonsignificant findings do not markedly differ from those reporting significant modulation of CSE.
