简要总结
The brain activity induced by a sensory stimulus and measured by magnetoencephalography will be compared before and after exposure to millimeter waves. We hypothesize that brain activity is modified after exposure to millimeter waves. The neuromodulatory effects of millimeter waves may lead to future development on therapeutic management in anxiety and pain.
详细描述
Several studies showed clinical efficacy of millimeter waves in pain management, with no side-effects.
However, its mechanism of action is still partly unknown. Preclinical studies showed that the use of millimeter waves near highly-innervated areas stimulates subcutaneous receptors, even at low power.
To achieve safe millimeter wave stimulation, we will use a bracelet (Remedee Labs) emitting millimeter waves, that has been developped for human use. It complies with radiofrequency exposure regulation (CE-marked).
This study aims to provide a better understanding of the mechanism by which millimeter waves interact with somatosensory system in brain.
For this purpose, the analysis of brain activity will focus on somatosensory responses elicited by electrical stimulation of the right thumb.
