• Direct current stimulation promotes BDNF-dependent synaptic plasticity: Potential implications for motor learning (2010, unknown): “DCS was applied in parallel to the vertical M1 fibers (Figure 1A) at a field strength ( 0.75 mV/ mm) in the lower range of the estimated field strengths of tDCS used in human M1 (0.22 [Miranda et al., 2006] to 7.7 mV/mm [Wagner et al., 2007]).”
• Transcranial direct current stimulation: State of the art 2008 (2008, background): “However, the effects of small electrodes could differ qualitatively due to: (a) differential shunting of current in the scalp; (b) greater edgeeffect relative to the overall electrode area (antagonistically oriented electric fields in the immediate vicinity of the electrodes(28)); and other factors.”
• Clinical Research with Transcranial Direct Current Stimulation (tDCS): Challenges and Future Directions (2011, unknown): “Evidence from modeling studies suggests that for typical tDCS significant amounts of current can reach broad cortical areas especially between and under the electrode surface.(12,13) Modeling studies also show that electrode montage is critical to the amount of current shunted through the skin.”
• Physiological and modeling evidence for focal transcranial electrical brain stimulation in humans: A basis for high-definition tDCS (2013, methodology): “HD-tDCS4×1 model The typical model settings as established previously were used (Datta et al., 2009; Miranda et al., 2006; Wagner et al., 2007), and the aforementioned TES4×1 motor montage was solved for HD-tDCS4×1.”
• The electric field in the cortex during transcranial current stimulation (2013, methodology): “In recent studies MR images were used to generate more realistic head models (Datta et al., 2009, 2010, 2011; Sadleir et al., 2010; Suh et al., 2012; Wagner et al., 2007).”
• Gyri –precise head model of transcranial DC stimulation: Improved spatial focality using a ring electrode versus conventional rectangular pad (2009, unknown): “In the case of direct current (DC) stimulation, induced cortical currents/EFs have been shown to modulate the firing properties of neurons and ''condition'' neuronal excitability.”
• Transcranial alternating current stimulation: a review of the underlying mechanisms and modulation of cognitive processes (2013, methodology): “Later approaches used more realistically shaped head models that were derived from MRI recordings (Holdefer et al., 2006; Wagner et al., 2007).”
• Battery powered thought: Enhancement of attention, learning, and memory in healthy adults using transcranial direct current stimulation (2014, unknown): “…current densities are seen for both the anode and the cathode at the edgenearest to the opposing electrode, and greater shunting though the scalp is thought to occur for smaller electrodes, though this can be overcome with increased current density (Miranda et al., 2009; Wagner et al., 2007).”
