Studies of the normal brain and nervous system

Summary

Background: Electromagnetic brain stimulation techniques have been used to map brain areas, to treat psychiatric disorders such as depression and rehabilitation. Often to see the changes of activation or inhibition of brain areas or to assess any change in synaptic plasticity induced by these stimuli, functional magnetic resonance imaging (fMRI) is used. Methods This double blind randomized pilot study, is the first study to examine with functional magnetic resonance imaging (fMRI) the effects on brain activity of voluntary healthy subjects, following a single, very low power 250 ms transcutaneous radio electric asymmetric conveyer (REAC) pulse. The primary target of this study was to assess if the REAC pulse, well below the temporal resolution of fMRI, might show some effect on the brain and particularly on cerebellum activity.

Plain Language Summary

Simplified for easier understanding

This study is using brain imaging (functional MRI, or fMRI) to look at what happens to brain activity when healthy volunteers receive a very brief, very low-power radioelectric pulse (called a REAC pulse). This type of pulse lasts only 250 milliseconds — less than the blink of an eye — and is completely painless. The goal is to see if this tiny signal has any measurable effect on brain activity, particularly in the cerebellum (the part of the brain that controls coordination). You may be eligible if: - You are between 18 and 55 years old - You are healthy with no medical conditions You may NOT be eligible if: - You have any health conditions (only healthy people are eligible) - You are outside the age range of 18–55 Talk to your doctor about whether this trial might be right for you.

This is a simplified summary. Always discuss eligibility with your doctor before enrolling in a clinical trial.
