No significant relationships were observed between rs-FC and brain activity in the tACS group (all p values > 0.05). Pairwise comparisons revealed a higher phosphenes occurrence in the tACS group in comparison to the tDCS group (p = 0.002, Fisher’s exact test; see Supplementary Table S1).

In the real stimulation groups, the current was supplied during 20 min, which covered the rs-fMRI acquisition and the first tb-fMRI sequence.

For the Fisher Wallace tACS device, the device’s basis in general is less well-understood than tDCS devices like TheBrainDriver and has a lack of electrophysiological evidence. The group-mean activity maps obtained from each contrast (1 > 0-back, 2 > 0-back, and 3 > 0-back) in the sham group (considered as the ‘reference’ WM brain patterns) are additionally displayed in SM (Supplementary Figure S3).

All study procedures were approved by the Institutional Review Board (IRB 00003099). While all these advantages sound top-notch, both devices do have some of their unique disadvantages. Let’s take a look at the two specific devices we will be addressing in this article. (2012). Philos. 6, 424–432. Brain Stimul. Sci. In many ways tACS is similar to tDCS as a neuromodulatory technique, but instead of applying a direct electrical current, tACS oscillates a sinusoidal current at a chosen frequency to interact with the brain’s natural cortical oscillations. Conversely, tACS effects were driven by neural increases online as compared to post-stimulation. At the highest WM load, subjects who received tDCS showed lower activity as compared to tACS in right frontal areas only (Figure 6B). Beyond their immediate impact, both techniques display after-effects that can outlast the period of stimulation, probably due to their capability to induce neuroplasticity-like processes (Nitsche and Paulus, 2001; Liebetanz et al., 2002; Nitsche et al., 2003; Monte-Silva et al., 2013; Vossen et al., 2015; Kasten et al., 2016; Wischnewski et al., 2019). We selected 6 Hz as this frequency has been widely used in recent tACS WM investigations (i.e., Polanía et al., 2012; Alekseichuk et al., 2016; Violante et al., 2017; Brauer et al., 2018; Röhner et al., 2018; Lang et al., 2019).

While all these advantages sound top-notch, both devices do have some of their unique disadvantages.

Keywords: cerebellum, tDCS, tACS, intensity, electrode placement, sham, offline vs. online, anodal vs. cathodal Introduction During the past 15 years a high number of studies have shown that transcranial Direct Current Stimulation (tDCS) is a simple and robust technique to modulate cortical excitability of the human brain (Nitsche and Paulus, 2011 ; Brunoni et al., 2012 ). Rs-FC was differentially modulated with respect to the specific tES protocol. However, tDCS appeared to strengthen this characteristic medial prefrontal deactivation pattern.

The FMRIB Software Library (FSL; version 6.001) and the Analysis of Functional NeuroImages (AFNI2) were used for preprocessing and analyzing neuroimaging data. Regarding the differences in each fMRI WM task, during the online fMRI WM task, tACS engaged distributed neural resources which did not overlap with the WM-dependent activity pattern, but with some posterior DMN regions. Int. (3) In the online fMRI WM task, tACS induced distributed neural activity which was not accommodated within the WMN, but overlapping certain posterior DMN areas.

However, both effects seem to focus on DMN regions and the WM network-DMN shift, which are highly affected in aging and disease. (4) In the post-stimulation fMRI WM task, tDCS strengthened expected medial prefrontal DMN deactivations, which correlated with faster responses. Working memory dysfunction in obsessive-compulsive disorder: a neuropsychological and functional MRI study. Furthermore, neural activity changes were found in a cognitive load-dependent manner, were tACS engaged distributed neural resources in low load conditions, while at the highest demanding load, activity increases were only evident bifrontally. Like . 1, 206–223. A questionnaire of tES-related adverse events was administered at the end of the experimental session [adapted from Brunoni et al., 2011; Figure 1C; see also Supplementary Material (SM)]. Altogether, prefrontal theta tACS during stimulation seemed to disrupt the characteristic WMN-DMN shift during externally oriented tasks (i.e., via a poorer DMN suppression, particularly within its posterior nodes). 38, 433–447. doi: 10.1002/hbm.20131, Pahor, A., and Jaušovec, N. (2014). During the online fMRI n-back task performance, participants who received tACS exhibited larger brain activity compared to those who received sham in the three contrasts of interest.

Int. Nevertheless, and despite this promising developments, data is still inconclusive, particularly in healthy populations (Tremblay et al., 2014; Hsu et al., 2015; Nilsson et al., 2015; Mancuso et al., 2016; Hill et al., 2017; Medina and Cason, 2017; Imburgio and Orr, 2018). However, the comparability of these approaches at the level of large-scale functional networks has not been thoroughly investigated. Notable inter- and intra-individual variability has been seen in response to distinct non-invasive brain stimulation protocols (i.e., Hamada et al., 2013; López-Alonso et al., 2014; Martin-Trias et al., 2018). Alternatively, it can make the brain less active or inhibitory, which is known as cathodal tDCS.

Although it is still considered an ‘experimental’ form of brain stimulation just like tACS, it has been well-researched as valuable for the treatment of a variety of neuropsychiatric conditions.

Right and below: plots of mean BOLD signal values at the fMRI clusters considering sham, tDCS and tACS where significant differences between groups were found. (2008). These results might be in line with the notion that tDCS increases neural efficiency on brain dynamics (Holland et al., 2011; Meinzer et al., 2012).
