Genomic Information Systems

In global information system age, the most important information is personal genomic information and the most important system is nervous system that includes the central nervous system (brain and spinal cord), peripheral nervous system (body voluntary control), sympathetic nervous system (autonomic "flight-or-fight"), and parasympathetic nervous system (autonomic "rest-and-digest").

A person's genome encodes instructions for nervous systems and other body systems such as the endocrine system, muscular system, digestive system, reproductive system, circulatory system, immune system, lymphatic system, respiratory system, and urinary system. Each system is formed by different organs, each organ is formed by different cell types, and each cell type is formed by networks of expressed special genes that interact and adapt to environmental cues and work robustly for our survival.

By analogy with a computer, genetic composition is like hardware and expressed gene network is like software. Of approximately 25,000 genes in human, each gene represents a unique software that is controlled at multiple layers of RNA transcription regulation, mRMA splicing, editing and degradation, protein synthesis, modification and degradation, etc. Genomic information systems form pathways of networks and have functions of self-repair, self-learning, and self-propagation. Knowledge of our personal genomic information will help us and doctors to prevent and treat chronic neurological diseases.
