Clinical Research with Transcranial Direct Current Stimulation (tDCS): Challenges and Future Directions (2011, neutral): “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.”
Transcranial Alternating Current Stimulation Enhances Individual Alpha Activity in Human EEG (2010, methodology): “(2006) used inverse modelling to show that 1mA of tDCs leads to about 110 mV/mm of electric fields in cortex, thus probably staying below the threshold for action potentials [55].”
Direct current stimulation promotes BDNF-dependent synaptic plasticity: Potential implications for motor learning (2010, positive): “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]).”
The electric field in the cortex during transcranial current stimulation (2013, methodology): “The field under the electrodes is largely perpendicular to the cortical surface whereas the field between the electrodes is largely tangential to the cortex (Datta et al., 2008; Miranda et al., 2006).”
Transcranial alternating current stimulation: a review of the underlying mechanisms and modulation of cognitive processes (2013, methodology): “Miranda et al. (2006) demonstrated that 2 mA of tDCS results in 0.1 A/m2 of intracranial current density 1 corresponding to an electric field of 0.22 V/m. Neuling et al. (2012b) used a very fine-grained finite element model to show that 1 mA of tDCS/tACS applied to human visual cortex results in an…”
Gyri –precise head model of transcranial DC stimulation: Improved spatial focality using a ring electrode versus conventional rectangular pad (2009, neutral): “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.”
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.”
Electric field calculations in brain stimulation based on finite elements: An optimized processing pipeline for the generation and usage of accurate individual head models (2013, methodology): “The electric field generated by tDCS is given by ~E 1⁄4 ~ r/ [Miranda et al., 2006].”
Combining non-invasive transcranial brain stimulation with neuroimaging and electrophysiology: Current approaches and future perspectives (2016, neutral): “In addition, the current density is not homogeneously across the electrode-skin interface and is likely also affected by the electrode and gel properties, making the stated values a very coarse estimate (Miranda et al., 2006; Saturnino et al., 2015).”
Transcranial direct current stimulation: A computer-based human model study (2007, result): “The maximum cortical current density magnitudes are of the same order of magnitude of those cases recently published by Miranda et al. (2006).”
