The main questions it aims to answer are:\n\n1. What are the effects of non-invasive brain stimulation on neuronal plasticity in the visual cortex of adults with amblyopia, and does it produce lasting changes?\n2. Do cumulative sessions of non-invasive brain stimulation influence neural plasticity and higher-order visual functions in adults with amblyopia?\n\nThe investigators hypothesize that non-invasive brain stimulation will show a positive cumulative effect after five (5) consecutive days of stimulation on visual perception and function in adults with amblyopia.\n\nParticipants will be randomized into one of two treatment groups:\n\n1. High-frequency transcranial random noise stimulation (hf-tRNS).\n2. Sham stimulation.\n\nResearchers will compare baseline measurements of crowded visual acuity, contrast sensitivity, stereoacuity, phosphene thresholds, global motion perception, form pattern recognition and pattern-reversal visual evoked potentials (VEPs) to post-treatment measurements for each group.",[93],"Amblyopia",[93,95,96,97,98],"Non-invasive Brain Stimulation","Transcranial Random Noise Stimulation","Visual Perception","Visual Evoked Potentials","2024-12-09",{"date":101,"type":102},"2024-12-12","ACTUAL",{"date":104,"type":102},"2024-05-01",{"date":106,"type":87},"2028-12-31",{"name":5,"class":6},1]
