Transcranial Direct Current Stimulation Modulates Connectivity of Left Dorsolateral Prefrontal Cortex with Distributed Cortical Networks

Abstract: Studies have shown that transcranial direct current stimulation increases neuronal excitability of the targeted region and general connectivity of relevant functional networks. However, relatively little is understood on how the stimulation affects the connectivity relationship of the target with regions across the network structure of the brain. Here, we investigated the effects of transcranial direct current stimulation on the functional connectivity of the targeted region using resting-state fMRI scans of t… Show more

“…Jones et al, 2020; K.T. Jones et al, 2020; Kim et al, 2021 ; Jones et al, 2017 ; Reinhart and Nguyen, 2019 ), and results show promise for enhancing ( Alekseichuk et al, 2016 ) and rescuing ( Reinhart and Nguyen, 2019 ) working memory across the lifespan. In younger adults, PFC theta tACS also shows promise for improving sustained attention, related to strengthened alpha (8–12 Hz) connectivity in the dorsal attention network ( Rostami et al, 2021 ).…”

“…At each stage, the participants were arranged to complete a set of pre- and post- tDCS experiment ( Kim et al, 2021 ). At first, the participants underwent 8-min rsfMRI and 5-min T1 structural imaging, followed by the first visual attention search task.…”

“…Another study showed that tDCS (conducted on lDLPFC) could also induce a pairwise-level change in connectivity between the lDLPFC and the junction of the bilateral superior parietal lobule and inferior parietal lobule, which suggested that tDCS can also alter the connectivity between two specific brain regions ( Mondino et al, 2020 ). Furthermore, recent studies suggested that tDCS over the DLPFC could help modify the regional and global brain network dynamics by increasing network flexibility ( Zhou et al, 2020 ) and the characteristics of the lDLPFC as a subregion also could be modulated by tDCS at different network scales (as a subregion of the frontoparietal control network, i.e., FPCN, or as a part out of FPCN) ( Kim et al, 2021 ). In addition, the local blood oxygenation level-dependent (BOLD) signal activation in regions away from the stimulated area may show a significant change during the stop-signal task ( Sandrini et al, 2020 ), which may indicate that with the connection property or connectivity pattern changes induced by tDCS, the local state of the distal areas could also be affected.…”

“…MRI data were acquired at each session prior to and ∼30 min following the application of tDCS on a 3 Tesla (T) MRI (Discovery 750 W, GE Healthcare, Madison, WI) equipped with a 24-channel head coil. The MRI acquisition consisted of the following sequences: a 12-min resting-state functional MRI (fMRI) (Kim et al, 2021), three 10-min task fMRIs (Sherwood et al, 2018), T1-weighted MRI (6.5 min for session 1 pre-stimulation, 3.5 min for the remaining sessions), diffusion tensor imaging (DTI; 5 min), single-voxel magnetic resonance spectroscopy (MRS; 6 min), and resting ASL (5 min). As this work is part of a much larger study, we will only be presenting the resting ASL data herein.…”
