Theta band transcranial alternating current stimulations modulates network behavior of dorsal anterior cingulate cortex

Abstract Dorsal anterior cingulate cortex (dACC) is an important region in the processing of both cognition and affect. Recently, transcranial brain stimulation has been used to modulate cortical activity, but it is unclear whether this stimulation has a specific effect on dACC. Based on EEG evidenc...
