New publication on acute effects of tDCS on functional connectivity of working memory networks in older adults
The Woods Lab recently published a new peer-reviewed article in Frontiers in Aging Neuroscience on the acute impact of tDCS on working memory networks in older adults. The study found that functional connectivity in left dorsolateral prefrontal cortex and ventrolateral prefrontal cortex increases during stimulation of the frontal lobes during a challenging 2-back working memory task in older adults. In addition, these effects were specific to a more effortful/challenging working memory task vs. a less challenging task – suggesting state dependent effects of tDCS in the brain. Furthermore, the paper also provides evidence of time-dependent effects of tDCS on functional connectivity demonstrating that effects on brain connectivity were present during, but not after tDCS.
