In the microscopic world, a pyramid woven from nano-scale transparent carbon fiber stands in the ocean of neurons. Bioelectric currents flash on the surface of the pyramid, and complex neural network structures can be seen inside. Countless tiny light spots shuttle through the transparent structure, simulating the sparks of thought. Colorful neurotransmitter molecules float around the pyramid, constantly changing their positions as the electrical signals are transmitted, presenting a dynamic and vital microscopic art scroll.
