Using HD-tDCS to Study Brain Connectivity

Modulating Functional Brain Connectivity Using High Definition Transcranial Direct Current Stimulation (HD-tDCS)

Not applicable Interventional University of Manitoba · NCT05959551

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.

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.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy individuals without any history of neurological or psychiatric disorders.

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.

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 performed: 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.
