Multiscale Coupling of Transcranial Direct Current Stimulation to Neuron Electrodynamics: Modeling the Influence of the Transcranial Electric Field on Neuronal Depolarization

Figure 13

Transmembrane voltage increase in plane longitudinally through the motor cortex ipsilateral to the anode; viewing perspective is from the left posterior with the head facing towards the left. The arrows in (a) locate the primary motor cortex.

(a) = 1 ms

(b) = 10 ms

(c) = 20 ms

(d) = 50 ms
