We have visual motor imitation and auditory lingual imitation, imitation by central vision is more accurate than lateral vision, unconsciousness doesn't share in imitation. Imitation has three stages 1- Visual stage , 2- Simulatory stage (inner seeing for planning) , 3- Executive motor stage. We have three kinds of memory (sensory, simulatory, motor) and each kind has nine types of memory. First types of memory use basal ganglia dopamine power and the last types use ventral pallidum dopamine power. The most important component in motivation is reward system (LOFC, Nac, Insula), then survival system and autonomic visceral system.
