Summary

This study aims to understand how the brain processes what we see, like faces, tools, and scenes. Healthy volunteers aged 18-50 will perform visual tasks while having brain scans (MRI) and receiving mild brain stimulation (TMS or tES). The goal is to map which brain areas handle different aspects of vision, not to test a treatment.
