Summary
Transcranial static magnetic stimulation (tSMS) shows potential for safely modulating brain excitability. This non-invasive technique may offer therapeutic benefits for conditions involving cortical hyperexcitability.
Area of Science:
- Neuroscience
- Biophysics
- Neuromodulation
Background:
- Transcranial static magnetic stimulation (tSMS) is an emerging technique for non-invasive brain modulation.
- Understanding its effects on the central nervous system (CNS) is crucial for therapeutic applications.
Purpose of the Study:
- To systematically review the literature on tSMS in humans and animals.
- To evaluate its effects on CNS areas, neural excitability, behavior, and biological impacts.
- To explore future possibilities of tSMS.
Main Methods:
- Comprehensive literature search across multiple databases (PubMed, Scopus, etc.).
- Independent study selection, data extraction, and quality assessment by three reviewers.
- Adherence to Cochrane Handbook and PRISMA guidelines.
Main Results:
- Analysis of 27 studies indicates tSMS has an inhibitory effect on various CNS regions (motor, somatosensory, visual cortex, cerebellum, spinal cord).
- Observed behavioral effects are transient and area-dependent, including altered visual discrimination and improved somatosensory perception.
- tSMS demonstrates therapeutic potential for pathologies characterized by cortical hyperexcitability.
Conclusions:
- tSMS is a promising, safe, and non-invasive tool for modulating cerebral excitability.
- Further research is needed to elucidate precise mechanisms of action and expand clinical applications.
