These vision problems make everyday life more difficult-for example, when reading, driving, or moving around safely. However, there is currently no effective therapy to improve visual field defects.\n\nPrevious training methods have focused on maximizing brain activity during a task. However, new findings show that the best performance is achieved when the brain is already in a state of high communication before the task. Our research shows that people can learn to increase communication between brain regions through neurofeedback.\n\nStudies have shown that neurofeedback can help people after a stroke: it improves the coordination of brain areas that are important for movement, thereby helping to increase mobility. Building on these findings, this study investigates whether EEG neurofeedback can support the visual centers in the brain to improve vision in patients with chronic visual field defects. The main objective of the study is to evaluate the effectiveness of neurofeedback in improving visual field defects. More specifically, the investigators are investigating the development of visual ability (expansion of the visual field, contrast sensitivity).",[27],"Visual Field Defect Homonymous Bilateral",[29,30,31,32],"stroke","neurofeedback","network","EEG","RECRUITING","2026-04-28",{"date":36,"type":37},"2026-04-29","ACTUAL",{"date":39,"type":37},"2025-11-17",{"date":41,"type":21},"2028-04-30",{"name":43,"class":44},"Adrian Guggisberg","OTHER",{"id":46,"slug":47,"hasResults":11,"nctId":48,"briefTitle":49,"officialTitle":49,"acronym":50,"eligibilityCriteria":51,"healthyVolunteers":52,"sex":16,"minAge":53,"maxAge":54,"enrollmentInfo":55,"targetDuration":4,"studyType":22,"phases":57,"briefSummary":58,"conditions":59,"keywords":61,"overallStatus":33,"whyStopped":4,"lastUpdateSubmitDate":64,"lastUpdatePostDateStruct":65,"startDateStruct":66,"completionDateStruct":68,"leadSponsor":70,"locationsCount":71},"100635547","effect-of-transcranial-random-noise-stimulation-on-the-performance-in-language-tasks-100635547","NCT07554105","Effect of Transcranial Random Noise Stimulation on the Performance in Language Tasks","tRNSlang","Inclusion Criteria:\n\n* Age: 18-35 years or 60-90 years\n* Native French speakers\n* Right handed\n* Willing and able to provide informed consent\n* Normal or corrected-to-normal vision and hearing\n\nExclusion Criteria:\n\n* History of neurological or psychiatric disease\n* Regular consumption of benzodiazepines, neuroleptics, or psychoactive drugs\n* Major language deficit, developmental language disorder, arthropathies and other mechanical language impairments\n* Inability to understand or follow study procedures\n* Contraindications to brain stimulation, such as\n\n  * History of epilepsy or severe migraine\n  * Pacemaker or other active implants\n  * Metallic objects in the head\n  * Skull breach such as craniotomy\n  * Pregnancy",true,"18 Years","90 Years",{"count":56,"type":21},90,[24],"Language is an essential part of daily life, enabling us to communicate, understand others, read, and learn. Certain brain injuries can disrupt these abilities, and current treatments do not always lead to a full recovery. To improve future therapeutic approaches, it is necessary to better understand how the brain processes language and how its activity can be modulated.\n\nThis study aims to evaluate the effects of a non-invasive brain stimulation technique called transcranial random noise stimulation. This method involves applying a very weak electrical current to the scalp to modulate the activity of brain regions involved in language. It is commonly used in research and is considered safe when administered in accordance with current guidelines.\n\nHealthy adult volunteers will participate in this study. Each participant will take part in two sessions spaced about a week apart. During one session, active stimulation will be used, and during the other, placebo stimulation will be used. Placebo stimulation resembles the actual stimulation but has no active effect. Neither the participants nor the researchers will know which type of stimulation is being used during each session.\n\nDuring the sessions, participants will perform various language tasks, and their brain activity will be recorded using an electroencephalogram (EEG), a painless method.\n\nThis study does not provide any direct benefit to participants. The risks are low and limited to temporary sensations, such as a tingling sensation on the scalp. The results will provide a better understanding of how the brain processes language and could eventually contribute to the development of new rehabilitation approaches.",[60],"Healthy Adult Participants",[62,63],"language","tRNS","2026-04-20",{"date":34,"type":37},{"date":67,"type":37},"2026-03-17",{"date":69,"type":21},"2027-12-31",{"name":43,"class":44},1,""]
