All of information during the life of a creature could be stored in neural circuits. These circuits are emerged to control activity of genes and their interactions with medium. Thus, all of information of neurons within a neural network could be stored in genes so. Also, there is a chief gene which produces a circuit within the brain and decide about continuity of life. Infact, when, this gene becomes turn off, related neural circuit send the message of death to all organs and stop their activities. After death of a creature, by injecting it’s nucleus or DNA into an egg cell and using suitable conditions, one can turn on chief gene and other related genes and produce a new creature with the perception of environment and memory of initial creature. To test the method, we inject cells of dead birds into the egg cells and compare their signals with non-fertilized eggs.
