We have previously shown the efficacy of bi-anodal transcranial direct current stimulation (tDCS) over the prefrontal cortex (PFC) regions with extracephalic references placement in improving negative symptoms in schizophrenia. In this ancillary investigation, the effects of this intervention on insight levels, other clinical outcomes, cardio-respiratory and autonomic functions were examined and the potential of biomarkers for treatment response was explored.

双阳极 tDCS 对前额叶皮层区域的影响，头外参考放置对精神分裂症患者的洞察力水平、心肺和自主功能以及治疗反应的探索性生物标志物分析。

我们之前已经展示了双阳极经颅直流电刺激 (tDCS) 对前额叶皮层 (PFC) 区域的疗效，在改善精神分裂症的阴性症状方面，脑外参考放置。在这项辅助调查中，检查了这种干预对洞察力水平、其他临床结果、心肺和自主神经功能的影响，并探索了生物标志物对治疗反应的潜力。
