Such an association can then be used backward to retrieve a movement by anticipating its effects. These perception/action codes are also accessible during action observation. Other authors suggest a new notion of the phylogenetic and ontogenetic origin of action understanding that utilizes the motor system; the motor cognition hypothesis.
A motor program is an abstract metaphor of the central organization of movement and control of the many degrees of freedom involved in performing an action. Biologically realistic alternatives to the metaphor of the "motor program" are represented by central pattern generators .
From the year 2000 onwards, a growing number of results have been interpreted in favor of the common coding theory. For instance, one functional MRI study demonstrated that the brain's response to the 2/3 power law of motion (i.e., which dictates a strong coupling between movement curvature and velocity) is much stronger and more widespread tha
The gradient of motor unit force is correlated with a gradient in motor neuron soma size and motor neuron electrical excitability. This relationship was described by Elwood Henneman and is known as Henneman's size principle , a fundamental discovery of neuroscience and an organizing principle of motor control.
It is derived from the terms "ideo" (idea, or mental representation) and "motor" (muscular action). The phrase is most commonly used in reference to the process whereby a thought or mental image brings about a seemingly "reflexive" or automatic muscular reaction, often of minuscule degree, and potentially outside of the awareness of the subject.

ERP results also demonstrated a motor-to-semantics effect as brain markers of comprehension were modified by motor effects. [19] The Action-Compatibility Effect also states that the brain resources used to plan and carry out actions are also used in language comprehension; therefore, if an action implied in a sentence is different from the ...
