“…Figure 1B illustrates the anatomical references for SMA identification and the positions of the tDCS electrodes; stimulation was applied by using a neuroConn® DC-Stimulator Plus (model 0021) connected to two sponge electrodes, filled with saline solution (active 10.7 cm 2 , reference 100cm 2 in order to be functionally inefficient, according to Vollmann et al, 2013). Active electrode was placed over the SMA under the guidance of an MRI-based neuronavigation system (Softaxic Optic 2.0).…”

“…Thus, electrode montage (current intensity and/or direction of current flow) seems to be important for the positive effect on motor skill learning (for further discussion, see Chapter 4). Aside from M1, it has also been shown that anodal tDCS over the supplementary motor area can improve motor skill learning on a similar task, at least during a single training session (Vollmann et al, 2012). This is not surprising, given that the SMA is critically involved -like M1-in learning this task (J. Reis, unpublished data) and the close proximity of the SMA and M1 could lead to co-stimulation.…”

“…Although a few studies have found that anodal tDCS to the SMA (a motor area) improves motor planning behaviors [37][38][39][40], no previous studies have tested whether tDCS might facilitate the planning abilities of Broca's area (a speech/language area) during non-verbal motor tasks. In particular, this study will investigate whether anodal tDCS to Broca's area influences performance on a SRT, CRT, and dynamic balance aiming task.…”

Transcranial direct current stimulation (tDCS) has been investigated as a novel therapy for addressing motor, cognitive, and language deficits. While anodal tDCS to the primary motor cortex results in improved motor behaviors, few studies have examined if tDCS to other areas involved in motor output produces similar benefits. Although Broca's area is associated with speech production and grammar acquisition, it also contributes to motor planning and output in non-speech tasks. This study involved applying anodal tDCS to Broca's area and observing effects on non-verbal motor output. Twenty young adults completed two testing sessions separated by one week. Participants received either 30 minutes of 1.0 mA of anodal tDCS to Broca's area or sham stimulation. During stimulation (or sham), participants completed two tasks: (1) a limits of stability dynamic balance task and (2) a simple (SRT)/choice reaction time(CRT) tasks. Subjects who received tDCS to first performed significantly better on SRT and dynamic balance accuracy and showed a trend for dynamic balance speed when tested one week later compared to those who received sham stimulation first. These findings indicate that Broca's area is involved in the production of non-verbal motor behaviors and may have implications novel combined speech and movement therapy interventions.
