Common model of evolution for living cell and central nervous system.

Both living cell and central nervous system can be treated as objects similar to artificial neural networks, actively studied now. One can see deep analogies between evolutionary processes in these systems, and correspondences can be established between some phenomena and objects. These are: genome vs. memory, gene vs. symbol, cell type vs. image, mitosis vs. sleep, organism vs. perception state, species vs. language, fertilization vs. attention, meiosis vs. paradoxal sleep. There is reason to study these correspondences on more technical level being based upon network nature of the living cell and nervous system.
