“…After the FORCEtraining with tDCS with the anode placed over M1, using a questionnaire developed by Brunoni et al (2011) andFertonani et al (2010), we asked participants to report the presence and severity (none-mild-moderate-considerable-strong) of feelings of itchiness, tingling, headache, neck pain, scalp pain, burning, warmth/heat, pinching, iron taste, fatigue, concentration difficulties and acute mood changes. In addition, the start (beginning, middle or end of stimulation) and duration (stopped soon, in the middle or towards the end of the stimulation) of these sensations was questioned and participants were asked if the sensations influenced their performance (not at all, a little, considerably, much, very much).…”

Functional motor declines that often occur with advancing age -including reduced efficacy to learn new skills -can have a substantial impact on the quality of life. Recent studies using non-invasive brain stimulation indicate that priming the corticospinal system by lowering the threshold for the induction of long-term potentiation (LTP)-like plasticity before skill training may facilitate subsequent skill learning. Here we utilized 'priming' protocol, in which we used transcranial direct current stimulation (tDCS) applying the cathode over the primary motor cortex (M1) prior to the anode placed over M1 during unimanual isometric force control training (FORCEtraining). Older individuals who received tDCS with the cathode placed over M1 prior to tDCS with the anode placed over M1 concurrent with FORCEtraining showed greater skill improvement and corticospinal excitability increases following the tDCS/FORCEtraining protocol compared to both young and older individuals who did not receive the preceding tDCS with the cathode placed over M1. The results suggested that priming tDCS protocols may be used in clinical settings to improve motor function and thus maintain the functional independence of older adults.

“…At the end of both stimulation sessions, participants completed a tDCS sensation rating scale, which asked them to rate the duration of sensations and the intensity of itchiness, pain, burning, heat, pinching, iron taste and fatigue (adapted from Fertonani, Rosini, Cotelli, Rossini, & Miniussi, 2010). Responses showed that tDCS was well-tolerated and ratings of sensations confirmed that participants could not reliably distinguish when they had been receiving sham or active stimulation (no differences for any of the sensations, Table 2).…”

Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. that any effects were due to the influence of tDCS on long-term learning and not a direct consequence of short-term changes in neural excitability. We found that only a few exposures to the phonological forms of nonwords were sufficient to enhance nonword ISR overall compared to entirely novel items. Anodal tDCS during familiarisation further enhanced the acquisition of phonological forms, producing a specific reduction in the frequency of phoneme migrations when sequences of nonwords were maintained in verbal short-term memory. More of the phonemes that were recalled were bound together as a whole correct nonword following tDCS. These data show that tDCS to left temporoparietal cortex can facilitate word learning by strengthening the acquisition of long-term phonological forms, irrespective of the availability of a concrete referent, and that the consequences of this learning can be seen beyond the learning task as strengthened phonological coherence in verbal short-term memory.

Anodal and cathodal transcranial direct current stimulations (tDCS) are both established techniques to induce cortical excitability changes. Typically, in the human motor system, such cortical modulations are inferred through changes in the amplitude of the motor evoked potentials (MEPs). However, it is now possible to directly evaluate tDCS-induced changes at the cortical level by recording the transcranial magnetic stimulation evoked potentials (TEPs) using electroencephalography (EEG). The present study investigated the modulation induced by the tDCS on the motor system. The study evaluates changes in the MEPs, in the amplitude and distribution of the TEPs, in resting state oscillatory brain activity and in behavioral performance in a simple manual response task. Both the short-and long-term tDCS effects were investigated by evaluating their time course at~0 and 30 min after tDCS. Anodal tDCS over the left primary motor cortex (M1) induced an enhancement of corticospinal excitability, whereas cathodal stimulation produced a reduction. These changes in excitability were indexed by changes in MEP amplitude. More interestingly, tDCS modulated the cortical reactivity, which is the neuronal activity evoked by TMS, in a polarity-dependent and site-specific manner. Cortical reactivity increased after anodal stimulation over the left M1, whereas it decreased with cathodal stimulation. These effects were partially present also at long term evaluation. No polarity-specific effect was found either on behavioral measures or on oscillatory brain activity. The latter showed a general increase in the power density of low frequency oscillations (theta and alpha) at both stimulation polarities. Our results suggest that tDCS is able to modulate motor cortical reactivity in a polarity-specific manner, inducing a complex pattern of direct and indirect cortical activations or inhibitions of the motor system-related network, which might be related to changes in synaptic efficacy of the motor cortex.
