Hypothesis
Is magnetoencephalography (MEG) compatible with high frequency deep brain stimulation (DBS) in measuring brain activity?
Conclusion
MEG can successfully measure brain activity even during high frequency deep brain stimulation.
Supporting Evidence
- MEG recordings showed similar activation in motor areas during the patient's movements.
- Similar activations were observed in cortical and subcortical areas associated with pain.
- MEG can be used to study brain activity during high-frequency DBS.
Takeaway
This study shows that we can use a special brain scan to see how the brain works even when a device is sending strong signals to help with headaches.
Methodology
MEG was used to record brain activity in a patient with a DBS implanted while varying stimulation frequencies.
Potential Biases
Potential artefacts from the DBS device may affect the data, but were not detectable in the analysis.
Limitations
The study involved only one patient, and the findings may not be generalizable.
Participant Demographics
One 56-year-old male patient with a history of cluster headaches.
