Ultra-high resolution 3D rendering of the brain autophagy process in a minimalistic, scientific aesthetic. Display a semi-transparent brain, intricately detailed with visible brain cells undergoing autophagy. The background should be a soft gradient of pinkish-red, transitioning smoothly from darker tones at the edges to a lighter hue near the center, adding depth without overwhelming the visual. Each brain cell should have subtle, glowing edges in shades of purple and yellow, emphasizing active autophagy regions. Autophagy markers should appear as small, floating particles within the cells, illuminated in a gentle, warm yellow. The entire composition should be sleek and clean, with soft lighting and shadows to enhance clarity and give a calming, elegant look. No excessive details--keep the image balanced, minimalistic
