Left prefrontal neuronavigated electrode localization in tDCS: 10 –20 EEG system versus MRI-guided neuronavigation

Transcranial direct current stimulation (tDCS) involves positioning two electrodes at specifically targeted locations on the human scalp. In neuropsychiatric research, the anode is often placed over the left dorsolateral prefrontal cortex (DLPFC), while the cathode is positioned over a contralateral cephalic region above the eye, referred-to as the supraorbital region. Although the 10 –20 EEG system is frequently used to locate the DLPFC, due to inter-subject brain variability, this method may lack accuracy.
