研究目的:

探索单靶点楔前叶gamma-tACS对MCI患者情景记忆、情景性自传体记忆、工作记忆及情绪症状的影响及其量效关系;探索双靶点左侧DLPFC-楔前叶theta/gamma频段tACS对MCI工作记忆速度-准确性权衡的不同模式及核心加工成分的调控作用,并明确刺激引起脑可塑性改变的关键神经基础,为寻找有效的认知障碍物理调控靶点提供依据。  

Objectives of Study:

To explore the effects and dose-response relationship of single-target gamma-band transcranial alternating current stimulation (gamma-tACS) over the precuneus on episodic memory, episodic autobiographical memory, working memory and emotional symptoms in patients with mild cognitive impairment (MCI); to investigate the modulatory effects of dual-target theta/gamma-band tACS over the left dorsolateral prefrontal cortex (DLPFC) and precuneus on the distinct patterns of speed-accuracy trade-off and core processing components of working memory in MCI, and to identify the key neural basis underlying stimulation-induced brain plasticity changes, so as to provide evidence for identifying effective physical regulation targets for cognitive impairment
