The Brain Nerves series is based on the understanding coming from Zheng Guogu’s long term observation of the fundamental influences on activities of human consciousness. The artist sees the consciousness’ formless activities as one genre of energy, and represents the photic qualities of movements of energy using images in order to transform them into paintings directly perceptible to a viewer. The U-shapes corresponds to a person’s neural circuitries as well as the various forms of changing energies surrounding their neural circuitries. U-shapes also reveal the relationship between three different functions of the brain: left, right and cerebellum; reason, emotion and memory. The colors of U-shapes also reflect the intensities of the energy of the subjects’ consciousness, while all the different forms of connections generated between the left and right “U” reflect different states of the energy of consciousness. From here, we can trace the various appearances of consciousness energy in history and the natural laws of the progress of human civilizations.
