懸浮在未來城市上方、擁有霓虹血管的賽博神經元

A massive neural cell fused with dark cybernetic structures, glowing neon veins in shades of purple, teal, and crimson. The dendrites twist like high-voltage cables, covered in metallic textures and nanotech implants. Synapses flash with neon sparks, as if transmitting coded signals through the void. Around it hover small drone-like nanomachines with red scanning lights. Background: futuristic cyberpunk city lights fading into darkness, giving the neuron a mechanical-organic presence. Style: dark sci-fi, cyberpunk, ultra-detailed, high contrast.
