Conceptual visualization of a neural network composed entirely of digital circuits, with data streams pulsing through its intricate webwork. The brain-like structure is surrounded by holographic overlays displaying complex patterns and symbols that represent its thought processes. Neural network textures dance across the surface of each circuit board, while glitch effects simulate the unpredictability of organic neural activity. This futuristic composition showcases both the power and vulnerability of a purely digital mind, with layered depths hinting at the potential for further evolution and transformation.
