Figure 8. HD-tACS model, targeting rIPS.

Figure 8.

(A) Diagram of the electrode montage. Five parietal channels (CP2, P2, P4, Pz, POz) were selected from a standard 64-channel EEG cap. The blue and red dots, indicating opposite polarities, show the chosen stimulation polarity distribution. This distribution produces a current sink targeting right intraparietal sulcus (IPS). (B) The current flow model based on the selected montage, showing 2D coronal, axial and sagittal views of the stimulation reaching each position in the brain. The open white circle indicates the targeted Montreal Neurological Institute coordinate (24, -70, 41), based on a previous fMRI study that mapped the location of human IPS (Swisher et al., 2007). (C) Three views of the 3D model simulation.
