A 3D render of a sci-fi baroque concept design featuring an anatomically correct brain device encased within a lush, verdant terrarium. The brain, intricately detailed, is surrounded by steampunk elements like brass gears, copper tubing, and polished mahogany panels, all finely crafted with ornate patterns. The terrarium's glass is magnified, offering a hyper-detailed view of the neural network intertwined with miniature ecosystems and flowing bioluminescent circuits. Scientific instruments with glowing dials and antique-styled knobs are integrated into the design, enhancing the futuristic yet vintage aesthetic. The entire composition is photorealistic, capturing the harmonious blend of organic and mechanical, life and invention, with a touch of ethereal luminescence.
