Conceptual visualization of a neural network forming a galactic entity, incorporating data streams as cosmic energy flows and neural patterns intertwine to create intricate stellar structures. Holographic overlays enhance the depth of the galaxy with symbolic abstractions that hint at the emergence of consciousness within its core. Futuristic composition features glitch effects, highlighting the network's adaptive learning processes and evolution towards sentience. Layered depths suggest a complex system composed of countless neurons, each contributing to the formation of this stunning, cosmic-inspired AI phenomenon.
