“…Permutation test and Bayesian analysis provided evidence to learn and assess the differences between groups, which avoided test H0 in Null Hypothesis Significance Testing (NHST; Kruschke, 2014). We conducted Bayesian estimation using JAGS 4.2.0 and R 3.4.0 following Kruschke's methods (Kruschke, 2013(Kruschke, , 2014, which has been applied in HD-tDCS study for statistical analysis (Hogeveen et al, 2016). We made region of practical equivalence (ROPE) between −1.0 and 1.0, and for more details, see Hogeveen et al (2016).…”

“…Recently, as a novel method, high-definition transcranial direct current stimulation (HD-tDCS) has been developed to compensate for the restrictions of conventional tDCS (Alam, Truong, Khadka, & Bikson, 2016). Having the advantage of high spatial resolution and focalizing, HD-tDCS typically applies a 4 × 1 ring electrode configuration to focus the targeted cortical region more precisely compared with conventional tDCS (Hogeveen et al, 2016). Faria et al (2011) noted that using four small return electrodes may be more effective than using the traditional large electrode.…”

BackgroundStudies on risk preferences have long been of great concern and have examined the neural basis underlying risk‐based decision making. However, studies using conventional transcranial direct current stimulation (tDCS) revealed that bilateral stimulation could change risk propensity with limited evidence of precisely focalized unilateral high‐definition transcranial direct current stimulation (HD‐tDCS). The aim of this experiment was to investigate the effect of HD‐tDCS focalizing the left dorsal lateral prefrontal cortex (DLPFC) on risk‐taking behavior during the Balloon Analogue Risk Task (BART).MethodsThis study was designed as a between‐subject, single‐blind, sham‐controlled experiment. University students were randomly assigned to three groups: the anodal group (F3 anode, AF3, F1, F5, FC3 returned), the cathodal group (F3 cathodal, AF3, F1, F5, FC3 returned) and the sham group. Subsequently, 1.5‐mA 20‐min HD‐tDCS was applied during the BART, and the Positive Affect and Negative Affect Scale (PANAS), the Sensation Seeking Scale‐5 (SSS‐5), and the Behavioral Inhibition System and Behavioral Approach System scale (BIS/BAS) were measured as control variables.ResultsThe cathodal group earned less total money than the sham group, and no significant difference was observed between the anodal group and the sham group.ConclusionsThese results showed that, to some extent, focalized unilateral cathodal HD‐tDCS on left DLPFC could change performance during risky tasks and diminish risky decision making. Further studies are needed to investigate the dose effect and electrode distribution of HD‐tDCS during risky tasks and examine synchronous brain activity to show the neural basis.

“…Several neuroimaging studies have supported this association by suggesting that the right inferior frontal gyrus (IFG) has a key role on the mediation of response inhibition (Aron et al, 2004; Garavan et al, 2006; Garavan et al, 1999; Kelly et al, 2004). Furthermore, studies using anodal transcranial direct current stimulation (tDCS) to the right IFG were able to increase response inhibition in stop signal tasks (Cunillera et al, 2014; Ditye et al, 2012; Hogeveen et al, 2016; Jacobson et al, 2011; Stramaccia et al, 2015). However, it is still unclear whether IFG control on proactive control involved in response inhibition is truly a lateralized function (i.e., left IFG would have a minimal impact) or if it depends on the successful mediation between right and left IFG.…”

This study examined the effects of bihemispheric and unihemispheric transcranial Direct Current Stimulation (tDCS) over the inferior frontal gyrus (IFG) on proactive control. Sixteen participants were randomized to receive (i) bihemispheric tDCS, with a 35 cm2 anodal electrode of the right IFG and a 35 cm2 cathode electrode of left IFG or (ii) unihemispheric tDCS, with a 35 cm2 anodal electrode of the right IFG and a 100 cm2 electrode of the left IFG or (iii) sham tDCS, while performing a prepotent inhibition task. There were significant speed-accuracy tradeoff effects in terms of switch costs: unihemispheric tDCS significantly decreased the accuracy when compared to bihemispheric, and sham tDCS, while increased response time when comparing to bihemispheric and sham tDCS. The computational model showed a symmetrical field intensity for the bihemispheric tDCS montage, and an asymmetrical for the unihemispheric tDCS montage. This study confirms that unihemispheric tDCS over the rIFG has a significant impact on response inhibition. The lack of results of bihemispheric tDCS brings two important findings for this study: (i) left IFG seems to be also critically associated with inhibitory response control, and (ii) these results highlight the importance of considering the dual effects of tDCS when choosing the electrode montage.

Networks underlying trait impulsivity: Evidence from voxel-based lesion-symptom mapping

et al. 2016

Impulsivity is considered a multidimensional construct that encompasses a range of behaviors, including poor impulse control, premature decision-making, and the inability to delay gratification. In order to determine the extent to which impulsivity and its components share a common network, we performed a voxel-based lesion-symptom mapping (VLSM) analysis in a large sample of patients (N=131) with focal, penetrating traumatic brain injuries (pTBI). Impulsivity was assessed using the Barratt Impulsiveness Scale (BIS-11), a standard self-report measure that allows for unique estimates of global impulsivity and its factor analysis-derived components (e.g., “motor impulsivity”). Heightened global impulsivity was associated with damage to multiple areas in bilateral prefrontal cortex (PFC), left superior, middle and inferior temporal gyrus, and left hippocampus. Moreover, we identified a cluster within the left PFC associated specifically with motor impulsivity (defined as “acting without thinking”). Our results are consistent with existing literature on bilateral prefrontal cortical involvement in behavioral impulsivity, but also provide new evidence for a more complex neuroanatomical representation of this construct, characterized by left-lateralized temporal and hippocampal involvement, as well as a left-lateralized prefrontal network specifically associated with motor impulsivity.

Abstract: Results support the use of both HD- and conventional tDCS to the IFC for improving response inhibition, providing empirical evidence that HD-tDCS can be used to facilitate performance on an executive function task.
