The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement. [ 1 ] [ 2 ] Peripheral structures may include skeletal muscles and neural connections with muscle tissues. [ 2 ]
A motor synergy is a neural organization of a multi-element system that (1) organizes sharing of a task among a set of elemental variables; and (2) ensures co-variation among elemental variables with the purpose to stabilize performance variables.
Optimal control is a way of understanding motor control and the motor equivalence problem, but as with most mathematical theories about the nervous system, it has limitations. The theory must have certain information provided before it can make a behavioral prediction: what the costs and rewards of a movement are, what the constraints on the ...
The central nervous system has two distinct ways of controlling the force produced by a muscle through motor unit recruitment: spatial recruitment and temporal recruitment. Spatial recruitment is the activation of more motor units to produce a greater force.
The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus. Motor cortex controls different muscle groups
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 .
Somatotopy is the point-for-point correspondence of an area of the body to a specific point on the central nervous system. [1] Typically, the area of the body corresponds to a point on the primary somatosensory cortex (postcentral gyrus). This cortex is typically represented as a sensory homunculus which orients the specific body parts and ...
In motor control, proprioceptors provide critical feedback to the central nervous system. Muscle spindles relay information regarding muscle stretch, Golgi tendon organs relay information regarding tendon force, and gamma motoneurons modulate muscle spindle feedback.
