I am looking for a free, user-friendly online tool or app to color or highlight brain regions such as the SMA, M1, insula, CB, PMv. Most tools I’ve found offer complex 3D MRI-style models, which are too advanced for my MSc lectures. I need something that provides simplified sketches or diagrams suitable for basic illustrative purposes in an educational setting. Ideally with networking features. Any recommendations for a straightforward tool?
Many thanks!
