《脑神经线》系列基于郑国谷在长期探测人类意识活动影响根源的过程中所产生的体悟，艺术家将无形的意识活动视为能量活动的一种，将能量活动的光感呈现为图形，从而转换成可令第三者直接感知的绘画。和脑神经回路相应的U形图形，不仅呈现脑部空间三种不同功能的关系：左脑、右脑和小脑；理性、感性和记忆，其颜色也反映出被测者意识能量的强度状态；而U形的左右之间所产生的各种连接形态反映了意识能量的不同状态，由此可以追踪意识能量在历史中的不同显现和在人类文明过程中的自然规律。

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.
