EFFERENCE COPY Did you know that your brain first creates a copy of the movement that your body performs? That's called Efference copy. What is Efference Copy? In physiology Efference Copy or efferent copy is a copy or picture of a movement formed inside the brain that is to be performed by an organism. These act as a movement producing signals generated by the individuals motor systems. In other words our brain is capable of predicting the response to an action. Combined with the sensory input from the individual's movement, Efference Copy helps one to adapt the postural changes by comparing the actual movement with the desired movement. Also it enables the individual to distinguish between self induced stimulus and external stimulus. i.e self movements and non self movements. Eg. One cannot tickle himself but gets tickled when someone else does it. Efferent copies are created by one's own movements and not those of others. Examples of Motor adaptations due to Efference
