Do ongoing cognitive demands affect the efficacy of transcranial electrical brain stimulation in young and older healthy adults?

大脑的经颅直流电刺激（tDCS）被广泛用于增强健康个体和神经系统疾病患者的认知和运动功能。不幸的是，tDCS的疗效在个体之间差异很大。该项目测试了一个假设，即正在进行的认知过程-特别是注意力-在调节tDCS对大脑功能的影响方面发挥着重要作用。所获得的知识将有助于完善tDCS作为临床和研究工具。

Transcranial direct current stimulation (tDCS) of the brain is widely used to enhance cognitive and motor function in healthy individuals and people with neurological disorders. Unfortunately, the efficacy of tDCS is highly variable between individuals. This project tests the hypothesis that ongoing cognitive processes – particularly attention – play an important role in regulating the effect of tDCS on brain function. The knowledge gained will help refine tDCS as a clinical and research tool.
