“…This effect is considered to be the result of its easy application, high safety, regulation of brain-derived neurotrophic factors and cell membrane transporters, and induction of more activity in the tDCS targeted area. It is also consistent with the findings by Green et al (2020) [30] and Dennison et al (2019), indicating that the constant electric current through local ion concentration changed the proteins passing through the membrane and changes in hydrogen cations, leading to enhanced performance of the intended areas. Finally, the results were consistent with those of Giustiniani et al [16] and Kim et al [21], demonstrating that tACS facilitated cognitive performance by increasing beta activity.…”

Objective The current study aimed to investigate the impact of transcranial alternating current stimulation (tACS) on working memory and selective attention in athletes with attention deficit hyperactivity disorder (ADHD). MethodsIn total 45 athletes with attention deficit hyperactivity disorder were randomly divided into three equal groups (sham, control and experimental groups). All participants in the sham and experimental groups received stimulations on the F3 and SO with a current of (10 HZ) 1 mA for 15 min over 10 sessions (P ≤ 0.05), and after 10 sessions, each group was retested. After 2 weeks, a follow-up test was performed according to the post-test using the Stroop test and N-BACK-(working memory test) to test statistical hypotheses (P ≤ 0.05). ResultsThe results of repeated measures analysis of variance revealed that applying tACS proved effective in improving the working memory and selective attention of ADHD athletes. ConclusionsThe study's findings indicated that the protocol of applying tACS 1 MA with 10 HZ improved the working memory and selective attention of ADHD athletes.

“…Typically, a direct or alternating current is used in tES investigations, thus called transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS). tES is known to enhance motor (Nitsche et al, 2003(Nitsche et al, , 2004Antal et al, 2007;Boros et al, 2008;Fritsch et al, 2010), behavioral (Wach et al, 2013;Hannah et al, 2019), and cognitive (Kuo and Nitsche, 2012;Fröhlich et al, 2015;Talsma et al, 2017;Green et al, 2020) performance.…”

Large interindividual variability in the effects of low-intensity transcranial electrical stimulation (tES) considerably limits its potential for clinical applications. It has been recently proposed that individualizing stimulation dose by accounting for interindividual anatomic differences would reduce the variability in electric fields (E-fields) over the targeted cortical site and therefore produce more consistent behavioral outcomes. However, improvement in behavioral outcomes following individualized dose tES has never been compared with that of conventional fixed dose tES. In this study, we aimed to empirically evaluate the effect of individualized dose tES on behavior and further compare it with the effects of sham and fixed dose stimulations. We conducted a single-blinded, sham-controlled, repeated-measures study to examine the impact of transcranial direct current stimulation on motor learning and that of transcranial alternating current stimulation on the working memory of 42 healthy adult individuals. Each participant underwent three sessions of tES, receiving fixed dose, individualized dose, or sham stimulation over the targeted brain region for the entire behavioral task. Our results showed that the individualized dose reduced the variability in E-fields at the targeted cortical surfaces. However, there was no significant effect of tES on behavioral outcomes. We argue that although the stimulation dose and E-field intensity at the targeted cortical site are linearly correlated, the effect of E-fields on behavior seems to be more complex. Effective optimization of tES protocols warrants further research considering both neuroanatomical and functional aspects of behavior.

“…First, the anodal tDCS induces an enhancement in the cortical excitability (i.e., LTPlike effect) by depolarizing the resting membrane potential. Second, the cathodal tDCS induces a reduction in cortical excitability (i.e., LTD-like effect) by hyperpolarizing the resting membrane potential [12,13].…”

Transcranial direct current stimulation (tDCS), a neuromodulation technique that is painless and noninvasive, has shown promising results in assisting patients suffering from brain injuries and psychiatric conditions. Recently, there has been an increased interest in home-based therapeutic applications in various areas. This study proposes a low-cost, internet of things (IoT)-based tDCS prototype that provides the basic tDCS features with internet connectivity to enable remote monitoring of the system's usage and adherence. An IoT-enabled microcontroller was programmed with C++ to supply a specific dose of direct current between the anode and cathode electrodes for a predefined duration. Each tDCS session's information was successfully synchronized with an IoT cloud server to be remotely monitored. The accuracy of the resulting stimulation currents was close to the expected values with an acceptable error range. The proposed IoT-based tDCS system has the potential to be used as a telerehabilitation approach to enhance safety and adherence to home-based noninvasive brain stimulation techniques.
