Special Issue Information

Dear Colleagues,

The use of non-invasive brain stimulation (NIBS) to modulate a broad range of cognitive processes and to ameliorate symptoms of several neuropsychiatric disorders is well established. While numerous empirical studies have investigated the effects of NIBS on neuromotor skills, executive functions, mood, and dysfunctional behaviours, few investigations have reported promising results on language and literacy skills. Hence, further empirical evidence is needed to confirm the potential of neurostimulation to be a successful approach to enhancing language skills. In a recent review, tDCS was found to selectively improve reading skills in poor readers and individuals with dyslexia, but not in typical readers, despite the used neurostimulation protocol.

This Special Issue aims to further our knowledge of the application of NIBS (e.g., tES, TMS) for the purpose of enhancing language and literacy skills. We aim to fuel the development of novel state-of-the-art NIBS protocols for interventions addressing language by exploring the variability in targeted cortical areas (electrode montages), number of sessions (single-session vs. multiple sessions), simultaneous application of behavioral interventions, and characteristics of the target population. We welcome empirical contributions on the effects of NIBS on language and/or literacy in both healthy and pathological populations (e.g., developmental dyslexia, acquired dyslexia, aphasia, language disorders) at any stage of the lifespan. We also welcome review and opinion articles that provide a detailed discussion of models or mechanisms that account for the effects of NIBS on language.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Brain Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Noninvasive brain stimulation techniques, such as transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS), paired with behavioral language therapy, have demonstrated the capacity to enhance language abilities in primary progressive aphasia (PPA), a debilitating degenerative neurological syndrome that leads to declines in communication abilities. The aim of this meta-analysis is to systematically evaluate the efficacy of tDCS and TMS in improving language outcomes in PPA, explore the magnitude of effects between stimulation modalities, and examine potential moderators that may influence treatment effects. Standard mean differences for change in performance from baseline to post-stimulation on language-related tasks were evaluated. Six tDCS studies and two repetitive TMS studies met inclusion criteria and provided 22 effects in the analysis. Random effect models revealed a significant, heterogeneous, and moderate effect size for tDCS and TMS in the enhancement of language outcomes. Findings demonstrate that naming ability significantly improves due to brain stimulation, an effect found to be largely driven by tDCS. Future randomized controlled trials are needed to determine long-term effectiveness of noninvasive brain stimulation techniques on language abilities, further delineate the efficacy of tDCS and TMS, and identify optimal parameters to enable the greatest gains for persons with PPA.
