Study Summary
This trial uses EEG, rTMS, MRI, and visual tests to study how our attention can affect how rTMS affects the brain. Participants observe visuals and make responses to changes.
Who is the study for?
This trial is for men and women aged 18 to 65 who understand English well, are either left- or right-handed, and have no history of neurological disorders or seizure risks. It's not suitable for those with MRI contraindications like metal implants, unstable medical conditions, head trauma history, active substance abuse, psychotic or bipolar disorders, pregnancy/breastfeeding status, or on certain medications.Check my eligibility
What is being tested?
The study tests how rTMS (a non-invasive brain stimulation technique) affects the brain's plasticity using EEG to measure responses while participants do visual tasks. The effect of attention on these changes is also studied by having participants focus on different parts of a visual field during the task.See study design
What are the potential side effects?
rTMS may cause discomfort at the stimulation site, headache, lightheadedness or fainting. Rarely it could induce seizures but this risk is minimized by excluding individuals with seizure histories or those taking medication that lowers seizure threshold.
