“…For example, Beeli et al ( 2008 ) reported that anodal tDCS to either the left or right DLPFC (10/20 EEG site F3 or F4) significantly improved the care of driving style as measures by following distance, average speed and number of errors. Similarly, Sakai et al ( 2014 ) reported that anodal tDCS to the right DLPFC significantly improved car-following and lane-keeping performance in a driving simulator task across days. Finally, Zhu et al ( 2015 ) reported that cathodal tDCS to the left DLPFC suppressed verbal working memory but improved motor learning.…”

“…Although reported effects of primary motor cortex (M1) stimulation on skill acquisition and procedural learning have been promising, these methods have primarily been investigated in standard psychological and motor tasks including the serial reaction time task (Nitsche et al, 2003 ), the tower of London task (Dockery et al, 2009 ); and sequential visual isometric pinch task (Reis et al, 2009 ). Increasing evidence for the application of tDCS to enhance real-world skills has been reported for vehicle control (Beeli et al, 2008 ; Sakai et al, 2014 ), golf (Zhu et al, 2015 ), threat detection in image analysis (Falcone et al, 2012 ), air traffic control (Nelson et al, 2014 ). tDCS has also decreased resumption lag after interruption (Blumberg et al, 2014 ), and maintained vigilance (McIntire et al, 2014 ) in real-world tasks.…”

Skill acquisition requires distributed learning both within (online) and across (offline) days to consolidate experiences into newly learned abilities. In particular, piloting an aircraft requires skills developed from extensive training and practice. Here, we tested the hypothesis that transcranial direct current stimulation (tDCS) can modulate neuronal function to improve skill learning and performance during flight simulator training of aircraft landing procedures. Thirty-two right-handed participants consented to participate in four consecutive daily sessions of flight simulation training and received sham or anodal high-definition-tDCS to the right dorsolateral prefrontal cortex (DLPFC) or left motor cortex (M1) in a randomized, double-blind experiment. Continuous electroencephalography (EEG) and functional near infrared spectroscopy (fNIRS) were collected during flight simulation, n-back working memory, and resting-state assessments. tDCS of the right DLPFC increased midline-frontal theta-band activity in flight and n-back working memory training, confirming tDCS-related modulation of brain processes involved in executive function. This modulation corresponded to a significantly different online and offline learning rates for working memory accuracy and decreased inter-subject behavioral variability in flight and n-back tasks in the DLPFC stimulation group. Additionally, tDCS of left M1 increased parietal alpha power during flight tasks and tDCS to the right DLPFC increased midline frontal theta-band power during n-back and flight tasks. These results demonstrate a modulation of group variance in skill acquisition through an increasing in learned skill consistency in cognitive and real-world tasks with tDCS. Further, tDCS performance improvements corresponded to changes in electrophysiological and blood-oxygenation activity of the DLPFC and motor cortices, providing a stronger link between modulated neuronal function and behavior.

“…However, in previous experiments with healthy subjects, dual-hemisphere tDCS elicited a more robust improvement in performance compared with single-hemisphere tDCS (Fujimoto et al, 2014a , b ). Therefore, it is reasonable to expect that dual-hemisphere tDCS represents a more powerful strategy for improving tactile spatial discrimination performance in stroke patients compared with single-hemisphere tDCS (Vines et al, 2008 ; Kasahara et al, 2013 ; Fujimoto et al, 2014a ; Sakai et al, 2014 ; Koyama et al, 2015 ). Future studies could clarify this issue by investigating the effects of single-hemisphere stimulation on behavior.…”

“…Dual-hemisphere tDCS, in which one hemisphere is excited while the other is inhibited, can have a powerful effect on behavioral performance (Vines et al, 2008 ; Kasahara et al, 2013 ; Fujimoto et al, 2014a ; Sakai et al, 2014 ; Koyama et al, 2015 ). This improved performance appears to be the combined consequence of increased excitability in one hemisphere and decreased excitability in the other, likely via interhemispheric connections.…”

In healthy subjects, dual hemisphere transcranial direct current stimulation (tDCS) over the primary (S1) and secondary somatosensory cortices (S2) has been found to transiently enhance tactile performance. However, the effect of dual hemisphere tDCS on tactile performance in stroke patients with sensory deficits remains unknown. The purpose of this study was to investigate whether dual hemisphere tDCS over S1 and S2 could enhance tactile discrimination in stroke patients. We employed a double-blind, crossover, sham-controlled experimental design. Eight chronic stroke patients with sensory deficits participated in this study. We used a grating orientation task (GOT) to measure the tactile discriminative threshold of the affected and non-affected index fingers before, during, and 10 min after four tDCS conditions. For both the S1 and S2 conditions, we placed an anodal electrode over the lesioned hemisphere and a cathodal electrode over the opposite hemisphere. We applied tDCS at an intensity of 2 mA for 15 min in both S1 and S2 conditions. We included two sham conditions in which the positions of the electrodes and the current intensity were identical to that in the S1 and S2 conditions except that current was delivered for the initial 15 s only. We found that GOT thresholds for the affected index finger during and 10 min after the S1 and S2 conditions were significantly lower compared with each sham condition. GOT thresholds were not significantly different between the S1 and S2 conditions at any time point. We concluded that dual-hemisphere tDCS over S1 and S2 can transiently enhance tactile discriminative task performance in chronic stroke patients with sensory dysfunction.

“…The authors concluded that excitation of the right and left DLPFC caused stronger executive control and a more careful driving style. Sakai et al (2014) found a better performance in car-following and lane-keeping after right-anodal/left-cathodal compared to left-anodal/right-cathodal tDCS. The authors conclude that this improvement is mediated by the enhancement of the right DLPFC where those spatial tasks are processed.…”

Objective: It could be demonstrated that anodal transcranial direct current stimulation (tDCS) of the left dorsolateral prefrontal cortex (DLPFC) enhances accuracy in working memory tasks and reaction time in healthy adults and thus may also have an influence on complex everyday tasks like driving a car. However, no studies have applied tDCS to psychomotor skills related to a standard driving test so far.Methods: 10 female and 5 male healthy adults without any medication and history of psychiatric or neurological illness were randomly assigned to two groups receiving active and sham stimulation in a double blind, cross-over study design. Standardized computerized psychomotor tests according to the German guidelines for road and traffic safety were administered at baseline. Then they performed the same tests during an anodal or sham tDCS of the left DLPFC in two separated sessions.Results: No significant improvements in skills related to driving performance like visual perception, stress tolerance, concentration, and vigilance could be shown after left anodal prefrontal tDCS. Side effects were low and did not differ between active and sham stimulation.Conclusions: The findings of our study indicate that left prefrontal tDCS may not alter driving skills affording more automated action patterns but as shown in previous studies may have an influence on driving behavior requiring executive control processes. This however has to be proved in future studies and within greater samples.
