Scientists probe Brain's feedback system with mild zaps
NCT ID NCT02816632
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed study in 76 healthy volunteers used brain scans (fMRI) and mild electrical stimulation (GVS) to explore how different types of feedback—like social or monetary cues—influence decision-making. The goal was to map the brain networks involved, with the hope of applying this knowledge to help people with conditions that disrupt feedback processing. No treatment was tested; this was purely a knowledge-gathering exercise.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Galvanic Vestibular Stimulation (GVS)
What this could lead to
If successful, this research could reveal how the brain processes different types of feedback, potentially guiding future treatments for conditions where this process is impaired.
What could go wrong
This is a small, early-stage study in healthy volunteers, not a treatment trial. The findings may not directly translate to clinical populations, and the brain stimulation technique is experimental.
