首先，回顾了进行tms-fmri实验研究的硬件和具体步骤。其次，探索了tms与fmri交织的技术，并总结了在fmri数据采集过程中tms产生的即时伪影。虽然许多先前发表的同步tms-fmri研究使用了tms与fmri交替采集，但本研究探索了在连续mri中使用tms以减少数据采集的低效性。

鉴于tms神经调控和fmri在评估脑功能活动方面的优势，fmri和tms结合（fmri-tms）研究tms的调控机理和临床效果已经成为近年来的热点。fmri-tms可以实时进行（即tms刺激的过程中记录fmri数据），也可以分开运行（即tms刺激前后记录fmri数据）。实时fmri-tms能极大地提高 ...

2024年5月23日 · Furthermore, task activation-guided TMS, as well as the use of RS-fMRI local metrics for targeted the specific abnormal brain regions, are considered a precise scheme for TMS targeting. Since 1.5 T MRI is more available in hospitals, systematic evaluation of the test-retest reliability and sensitivity of fMRI metrics on 1.5 T and 3 T MRI may ...

用于tms-eeg的皮层坐标，可以基于fmri的配准得到，fmri也可用于检测基于任务的激活，坐标对应到每个个体的结构成像。 即使文献已经确定了在任何认知任务中涉及的主要（即平均）区域，个体在结构和功能上的大脑整合也是不同的，因此使用任务进行功能定位 ...

2020年9月28日 · The concurrent transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) provides a non-invasive method for real-time evaluation of neuronal activity induced by TMS. It has the potential to identify brain areas of functional relevance to acute TMS, supporting causal brain connectivity and brain – behavior ...

Concurrent TMS-fMRI setup. (A) The TMS coil enters the back of the birdcage receive coil and is supported by (B) a custom arm. The supporting arm can be adjusted with 3 degrees of freedom. The arm attaches to a counterweight with three translations of spatial movement along the cardinal axes of the bore.

2022年4月21日 · In this respect, concurrent or simultaneous TMS-fMRI, in which TMS is applied during functional magnetic resonance imaging (fMRI), is a viable tool to gain insights, as it enables an investigation of the immediate effects of TMS. Concurrent application of TMS during neuroimaging usually causes severe artifacts due to magnetic field ...

2024年5月13日 · Concurrent TMS-fMRI provides a step-change in the toolkit of neuroscience research. Using non-invasive perturbation of ongoing human brain activity and simultaneous read-out of its effects across ...

2023年4月22日 · 文章浏览阅读782次。本文提出了同步tms-fmri的方法学挑战，并提供了在实验设计和后处理中尽量减少诱发伪影的指南。本研究主要考察两种前额叶-纹状体神经环路：在健康的人类参与者中，初级运动皮层(m1)投射到壳核和外侧前额叶皮层(pfc)投射到尾状核。结果发现，随着刺激强度的增加，tms参数化地 ...
