Using HD-tDCS to Study Brain Connectivity
Official title: Modulating Functional Brain Connectivity Using High Definition Transcranial Direct Current Stimulation (HD-tDCS)
Run by University of Manitoba · NCT05959551 · Data updated 2026-11-12
This study is testing how a brain stimulation technique called HD-tDCS affects brain connections in healthy people to see if it can be used better in treating conditions in the future.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are healthy individuals without any history of neurological or psychiatric disorders.
✕Probably not a fit
Patients with neurological or psychiatric diseases, abnormal MRI results, or those with metal implants or cardiac pacemakers will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to enhance our understanding of the neural effects of High Definition Transcranial Direct Current Stimulation (HD-tDCS) by recruiting healthy individuals for a series of neuropsychological assessments and MRI scans. Participants will receive HD-tDCS while undergoing MRI, with four different stimulation targets being tested against a sham group. After the stimulation, participants will be re-evaluated using standardized neuropsychological tests to assess any changes in brain connectivity and function. The goal is to improve the clinical applications of HD-tDCS based on the findings.
Why it matters
Potential benefit: If successful, this study could lead to improved therapeutic applications of HD-tDCS for various neurological and psychiatric conditions.
How similar studies have gone: While the use of HD-tDCS is gaining traction, this specific approach to studying its effects on brain connectivity is relatively novel and has not been extensively tested in similar studies.
