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 evidence that frontal midline theta activity is generated in dACC, we hypothesized that transcranial alternating current stimulation (tACS) with theta band frequency would modulate neural networks including dACC. In this study, we … Show more

“…Compared to traditional 1 × 1 TES, this minimizes the chances of stimulating confounding brain structures. Furthermore, previous literature targeting the dorsal anterior cingulate 68 , and recent computational modelling work, suggests that targeting deep cortical brain structures is possible with unique electrode configurations such as that utilized here 69 . The amplitude used in our TACS group is higher than that used most frequently in the TACS literature 34 .…”

“…We chose the DLPFC as a target since its location at the brain surface allows a more reliable stimulation. Stimulation of the dACC, in which due to its deep location is a more difficult target, has been done however [24, 53, 54]. Active conflict detection and resolution are attributed to dACC activity, whereas the adaptation after response is attributed to DLPFC activity [21].…”

“…It is worth noting that, following 10 min of bilateral θ‐tACS of the dorsolateral prefrontal cortex, this cortical hub decreased nodal efficiency (i.e. the ability to efficiently exchange information with other neural structures) and the capability to functionally integrate with other brain regions (Onoda, Kawagoe, Zheng, & Yamaguchi, ). However, such after‐effects were tested during resting state fMRI and further studies are needed to verify whether similar changes also occur during other cognitive performances.…”
