Abstract

Background/Objective

Source monitoring refers to the ability to determine the source of memories and encompasses three subprocesses: internal source monitoring, reality monitoring, and external source monitoring. Neuroimaging studies provide valuable insights about neural correlates of source monitoring, but the causal relationship between brain and behavior is lacking. This study aimed to identify brain circuits involved in source monitoring by synthesizing the effects of brain stimulation on source monitoring as a function of the targeted brain regions or circuits.

Method

We conducted a systematic review of interventional studies that have examined the effects of brain stimulation on source monitoring across six databases. The principal outcome was the difference of source monitoring performance between active and control stimulation conditions.

Results

23 studies (920 healthy participants and 54 patients with schizophrenia) were included. Our findings revealed the involvement of i) the lateral prefrontal and temporoparietal cortices in internal source monitoring, ii) the medial prefrontal and temporoparietal cortices in reality monitoring, and iii) the precuneus and the left angular gyrus in external source monitoring.

Conclusions

These findings deepen our understanding of the brain mechanisms of source monitoring and highlight specific stimulation targets to alleviate source monitoring deficits.

通过非侵入性脑部刺激揭示源监测的脑部机制：系统回顾

背景/目的来源监控是指确定记忆来源的能力，包括三个子过程：内部来源监控、现实监控和外部来源监控。神经影像学研究为源监控的神经相关性提供了有价值的见解，但缺乏大脑与行为之间的因果关系。本研究旨在通过综合脑刺激对源监控的影响，确定参与源监控的脑回路，并将其作为目标脑区或脑回路的功能。结果23项研究（920名健康参与者和54名精神分裂症患者）被纳入其中。我们的研究结果表明：i）外侧前额叶和颞顶叶皮层参与了内部信号源监测；ii）内侧前额叶和颞顶叶皮层参与了现实监测；iii）楔前叶和左侧角回参与了外部信号源监测。

期刊介绍： The International Journal of Clinical and Health Psychology is dedicated to publishing manuscripts with a strong emphasis on both basic and applied research, encompassing experimental, clinical, and theoretical contributions that advance the fields of Clinical and Health Psychology. With a focus on four core domains—clinical psychology and psychotherapy, psychopathology, health psychology, and clinical neurosciences—the IJCHP seeks to provide a comprehensive platform for scholarly discourse and innovation. The journal accepts Original Articles (empirical studies) and Review Articles. Manuscripts submitted to IJCHP should be original and not previously published or under consideration elsewhere. All signing authors must unanimously agree on the submitted version of the manuscript. By submitting their work, authors agree to transfer their copyrights to the Journal for the duration of the editorial process.
