Consciousness of action and self-consciousness

Most of our actions are executed under the control of automatic mechanisms. The feeling one has to have willingly caused an action and - by extension - self-consciousness, refer to the mechanisms prior to the feeling it lead to, i.e. a precedence resting on the slowness of processes leading to a conscious experience. Consciousness thus seems to have no immediate causal part to play on the nervous activity neither on behaviour, it interferes only later in order to structure the cognitive ego and keep some cohesiveness to the ego.
