Trial Summary

What is the purpose of this trial?

The purpose of this study is to understand how the brain controls movement and how Non-invasive Brain Stimulation (NIBS) with a technique called High-density transcranial direct current stimulation (HD-tDCS) can alter brain processes to improve behavior. Participants in this study will be randomized to either HD-tDCS with standard intervention or personalized dose-controlled multifocal network-targeted HD-tDCS. The hypothesis is that dexterous hand function will improve after a standard HD-tDCS dose and increase even more after personalized dose-controlled multifocal network-targeted HD-tDCS.

Eligibility Criteria

This trial is for healthy individuals interested in how brain stimulation can affect movement control. Participants should be willing to undergo non-invasive brain stimulation and fMRI scans. Specific eligibility criteria are not provided, so generally healthy adults may apply.

Inclusion Criteria

Participants should be English speakers

Participants should be right-handed

Participants should be able to provide written consent prior to admission

Exclusion Criteria

Participants with cochlear hearing implants

Participants with metal anywhere in the head that could increase the risk of serious injury (excluding braces, dental fillings, etc.)

I have been diagnosed with Parkinson's disease or Alzheimer's disease.

Treatment Details

Interventions

• High-density transcranial direct current stimulation (HD-tDCS) (Behavioural Intervention)
• Multifocal network targeted HD-tDCS (Behavioural Intervention)

Trial Overview The study tests if High-density transcranial direct current stimulation (HD-tDCS) can improve hand function. It compares standard HD-tDCS with a personalized multifocal version targeting specific brain networks, alongside monitoring with fMRI.

Participant Groups

Group I: Personalized dose-controlled multifocal network-targeted HD-tDCS. Experimental Treatment 2 Interventions

Participants will have three daily sessions.

Group II: HD-tDCS with standard intervention Experimental Treatment 2 Interventions

Participants will have three daily sessions.
