Generate a minimalistic 2D-rendered image of a human brain in top view with a simple, plain appearance. The brain should only have a glowing neon cyan outline, without any internal lines, partitions, or detailed structures. The background should be a smooth gradient transitioning from dark blue on the left to lighter shades of blue on the right. Ensure the brain outline glows vibrantly, standing out against the background. The overall style should be clean, modern, and minimalistic, with a focus on the glowing neon outline and the gradient background <https://s.mj.run/WEqK0UMnUC8>
