研究目的:

通过采用PANSS、RBANS和PSP量表,评估高精度经颅直流电刺激(HD-tDCS)在改善精神分裂症患者认知功能方面的临床疗效。 借助TMS-EEG技术,通过分析皮层反应性、局部兴奋/抑制平衡、振荡活动及脑区有效连接,探索HD-tDCS干预的神经机制。  

Objectives of Study:

1.To evaluate the clinical efficacy of HD-tDCS in improving cognitive function in schizophrenia patients using PANSS, RBANS, and PSP scales. 2.To explore the neural mechanisms of HD-tDCS intervention by analyzing cortical reactivity, local excitation/inhibition balance, oscillatory activity, and effective connectivity via TMS-EEG technology.
