Floating neural island with mostly flat dark surface. Central brain-like structure (pink/purple terracotta) with glowing neuron paths (glowstone lines). Synaptic connection arches (glass) bridging different sections. Scattered thought bubbles (floating glass spheres) containing mini galaxies. Nerve cluster pillars with pulsing redstone lamps. Flat electric pathways between structures. Detailed with pink/purple concrete, blackstone, redstone lamps, glass domes, and electrical spark particles. No fixed spawns.
