Brain zapping study seeks best way to boost brain flexibility
NCT ID NCT06735794
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how two different ways of giving a type of non-invasive brain stimulation called iTBS affect brain plasticity—the brain's ability to change and adapt. 29 healthy, right-handed adults aged 18 to 50 took part. Researchers compared a standard stimulation pattern with a spaced-out version and a fake (sham) stimulation to see which one caused the most change in brain activity.

Inclusion Criteria: 1. Age 18 years or above, and less than 51 years. 2. Right handedness, assessed using the Edinburgh Handedness Inventory (EHI). 3. Sufficiently proficient in English to complete the required study assessments, as per investigator judgement. 4. Willingness and capacity to provide informed consent. 5. Willingness to comply with all study procedures. Exclusion Criteria: 1. Age 17 years or less, or greater than 51 years, as brain plasticity is known to be affected by age. 2. Current use of any psychotropic medications (e.g. anti-depressants, anti-convulsants, anti-psychotics, etc.). 3. Contraindications to transcranial magnetic stimulation (TMS), as per investigator judgment. 4. Lifetime history of any Diagnostic and Statistical Manual of Mental Disorders (DSM-5) diagnosis, assessed using the Structured Clinical Interview for DSM-5 (SCID-5), except simple phobias. 5. Left handed or ambidextrous, assessed using the EHI, to minimize the heterogeneity in cortical excitability and plasticity. 6. Self-reported history of seizures and/or other major neurological conditions, as per investigator judgement, due to the risk of seizures associated with TMS in individuals with a heightened risk.
