 This study investigated the effectiveness of combining behavioral training with transcranial direct current stimulation, TDCS, for improving executive function in older adults. The results suggest that TDCS can enhance the effects of behavioral training by modifying the structure and function of the prefrontal cortex, as well as increasing connectivity between the prefrontal cortex and other regions of the brain. This suggests that TDCS may be used to improve cognition in aging populations. This article was authored by Doria Antonenko, Anna Elizabeth from Frydike Thams, and others.
