Visual Plasticity Following Brain Lesions Study
This study, called VIBRANT, is testing if a combination of transcranial random noise stimulation (tRNS) and perceptual learning-based training can help improve vision after brain damage. tRNS is a type of gentle electrical stimulation applied to specific areas of the brain. Perceptual learning-based training involves tasks like judging the direction of moving dots. You may be able to join if you are at least 18 years old and have vision loss due to a stroke, brain tumor, or traumatic brain injury. The study will measure changes in your ability to tell the direction of moving objects to see if the treatments are successful. The current recruitment status is unclear.
- Study design
- This is a double-blind, crossover study involving 30 participants. This means neither you nor the study staff will know which treatment you are receiving at a given time, and you will receive both the active stimulation and a sham (inactive) stimulation at different points.
- What's involved
- Your vision will be tested at the beginning and end of two different treatment periods, each lasting about a week.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your vision will be assessed within a week after each treatment period.

What this trial measures
- Change in Motion Discrimination PerformanceStudy visit 1 to 2 (within a week), and study visit 3 to 4 (within a week)
Change in accuracy on a computerized motion direction discrimination task programmed in the lab. The task assesses participants' ability to discriminate the direction of the peripherally presented moving dots at two locations (one within the blind field and the other at a mirror-symmetric location in the intact visual field). Accuracy is defined as the proportion of correct responses out of the total number of trials completed.
