Methods to Compare Predicted and Observed Phosphene Experience in tACS Subjects

Table 5

Predicted electric fields (EF) in the occipital lobe (OCC) for isotropic and anisotropic models. All computed electric fields were smaller than 28–79 V/m [7] or 1 V/m [9], the electric field action potential threshold for layer V pyramidal neurons and intact rat brain, respectively.
