简介：
Overview
This protocol outlines the use of repetitive transcranial magnetic stimulation (rTMS) targeting a specific subregion of the dorsolateral prefrontal cortex (DLPFC) identified through fMRI-based neuronavigation. This approach aims to enhance the precision of stimulation and potentially improve treatment outcomes for depression.
Key Study Components
Area of Science
- Neuroscience
- Psychiatry
- Neurostimulation
Background
- rTMS is a non-invasive brain stimulation technique.

- Further research is needed to validate these findings.
What is rTMS?
Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive procedure that uses magnetic fields to stimulate nerve cells in the brain.
How does fMRI assist in rTMS?
Functional MRI (fMRI) helps identify specific brain regions to target for stimulation, enhancing the precision of rTMS.
What is the significance of the DLPFC in depression?
The dorsolateral prefrontal cortex (DLPFC) is involved in mood regulation, and targeting it can improve treatment outcomes for depression.
Why is individual targeting important?
Individual targeting accounts for anatomical differences in the brain, which can affect the efficacy of rTMS treatments.
Who demonstrated the procedure?
The procedure was demonstrated by Min Zhang and Xin Luo, members of the research laboratory.
