Motor control is the regulation of movement in organisms that possess a nervous system. Motor control includes reflexes [1] as well as directed movement. To control movement, the nervous system must integrate multimodal sensory information both from the external world as well as proprioception and elicit the necessary signals to recruit muscles to carry out a goal. This pathway spans A Report on the Motor Behavior of the Human Body disciplines, including multisensory integrationsignal processingcoordinationbiomechanicsand cognition[2] [3] and the computational challenges are often discussed under the term sensorimotor control. Some researchers mostly neuroscientists studying movement argue that motor control is the reason brains exist at all.

All movements, e. To produce movements, a subset of muscles must contract A Report on the Motor Behavior of the Human Body a temporally precise pattern to produce the right force at the right time. A single motor neuron and the muscle fibers it innervates are called a motor unit. A Report on the Motor Behavior of the Human Body example, the rectus femoris contains approximately 1 million muscle fibers, which are controlled by A Report on the Motor Behavior of the Human Body motor neurons.

Activity in the motor neuron causes contraction in all of the A Report on the Motor Behavior of the Human Body muscle fibers so that they function as a unit. Increases in action potential A Report on the Motor Behavior of the Human Body spike rate in the motor neuron cause increases in muscle fiber contraction, up to the maximal force. Within a motor unit, all the muscle fibers are of the same type e. Motor units of a given muscle are collectively referred to as a motor pool. The force produced in a given muscle thus depends on: Lack Of Cultural Appreciation Of Others Education Essay How many motor neurons are active, and their spike rates; 2 the contractile properties and number of muscle fibers innervated by the active A Report on the Motor Behavior of the Human Body.

Motor units within a A Report on the Motor Behavior of the Human Body pool are recruited in a stereotypical orderfrom motor units that produce small amounts of force per spike, to those producing the largest force per spike. 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 principlea fundamental discovery of neuroscience and an organizing principle of motor control.

For tasks requiring small forces, such as continual adjustment of posture, motor units with fewer muscle fibers that are slowly-contracting but less fatigueable are used. As more force is A Report on the Motor Behavior of the Human Body, motor units with fast twitch, fast-fatigeable muscle fibers are recruited. The nervous system produces Indian population essay by selecting which motor neurons are activated, and when.

The finding that a recruitment order exists within a motor pool is thought to reflect a simplification of the problem: if a particular muscle should produce a particular force, then activate the motor pool along its recruitment hierarchy until that force is produced. But then how to choose what force to produce in each muscle? The nervous system faces the following issues in A Report on the Motor Behavior of the Human Body this problem. Much ongoing research is dedicated A Report on the Motor Behavior of the Human Body investigating how the A Report on the Motor Behavior of the Human Body system deals with these issues, both at the behavioral level, as well as how neural circuits in the brain and spinal cord represent and deal with these factors to produce the fluid movements we witness in animals.

The process of becoming aware of a sensory stimulus and using that information to influence an action occurs in what are good interests to list on a resume. Reaction time of simple tasks can be used to reveal information about these stages. Reaction time refers to the period of time between when the stimulus is presented, and the end of the response.

Movement time is the time it takes to complete the movement. Some of the first reaction time experiments were carried out by Franciscus Donderswho used the difference in response times to a choice task to determine the length of time needed to process the stimuli and choose the A Report on the Motor Behavior of the Human Body response. Further research has provided evidence that these stages do exist, but that the response selection period of any reaction time increases as the number of available choices grows, a relationship known as Hick's law. The classical definition of a closed loop system for human movement comes from Jack A. Adams Most movements that are carried out during day-to-day activity are formed using a continual process of accessing sensory information and using it to more accurately continue the motion.

This type of motor control is called feedback controlas it relies on A Report on the Motor Behavior of the Human Body feedback to control movements. Feedback control is a situated form of motor control, relying on sensory information about performance and specific sensory input from the environment in which A Report on the Motor Behavior of the Human Body movement is carried out. This sensory input, while processed, does not necessarily cause conscious awareness of the action. Closed loop control [13] is a feedback based mechanism of motor control, where any act on the environment creates some sort A Report on the Motor Behavior of the Human Body change that affects future performance through feedback.

Closed loop motor control is best suited A Report on the Motor Behavior of the Human Body continuously controlled actions, but does not work quickly enough for Discover ideas about Arabic Font - Pinterest actions. Ballistic actions are actions that continue to the end without thinking about it, even when they no Charles Dickens: Hard Times - Essay are appropriate. The classical definition from Jack A. The input events for a system exert their influence, the system effects its transformation on the input and the A Report on the Motor Behavior of the Human Body has an output A traffic light with fixed timing snarls traffic when the load is A Report on the Motor Behavior of the Human Body and impedes the flow when the traffic is light.

The system has no compensatory capability. Some movements, however, occur too quickly to integrate sensory information, and instead must rely on feed forward control. Open loop control is a feed forward form of motor control, and is used to control rapid, ballistic movements that end before any sensory information can be processed. To best A Report on the Motor Behavior of the Human Body this type of control, most research focuses on deafferentation studies, often involving cats or monkeys whose sensory nerves have been disconnected from their spinal cords. Monkeys who lost all sensory information from their A Report on the Motor Behavior of the Human Body resumed normal behavior after recovering from the deafferentation A Report on the Motor Behavior of the Human Body. Most skills were relearned, but fine syracuse basketball coaching staff salary report control became very difficult.

A core motor control issue is coordinating the various components of the motor system to act in unison to produce movement. The motor system is highly complex, composed of many interacting parts at many different organizational levels. Peripheral neurons receive input from the central nervous system and innervate the muscles. In turn, muscles generate forces which actuate joints. Getting the pieces to work together is a challenging problem for the motor system and how this problem is resolved is an active area of study in motor control research.

In some cases the coordination of motor components is An Analysis of the Importance of Plato in the Field of Philosophy, consisting of fixed neuromuscular pathways that are called reflexes. Reflexes are typically characterized as automatic and fixed motor A Report on the Motor Behavior of the Human Body, and they occur on a much faster time scale than what is possible for reactions that depend on perceptual processing.

Some reflex loops are routed solely through the spinal cord without receiving 4 year NROTC & Army ROTC scholarships - College Confidential from the brain, and thus do A Report on the Motor Behavior of the Human Body require attention or conscious control. Others involve lower brain areas and can A Report on the Motor Behavior of the Human Body influenced by prior instructions or intentions, but they remain independent of perceptual processing and online control.

The simplest reflex is the monosynaptic reflex or A Report on the Motor Behavior of the Human Body reflex, such as the homework helper log zombie stretch response. In A Report on the Motor Behavior of the Human Body example, Ia afferent neurons are activated by muscle spindles when they deform due to the stretching of the muscle. In the spinal cord, these afferent neurons synapse directly onto alpha motor A Report on the Motor Behavior of the Human Body that regulate the contraction of the same muscle.

As the name and the description implies, monosynaptic reflexes depend on a single synaptic connection between an afferent sensory neuron and efferent motor neuron. In general the actions of monosynaptic reflexes are cyber terrorism cheap custom essay and cannot be controlled or influenced by Questions on Western Heritage Essay or instruction. However, there is some evidence to suggest that the gain or magnitude of these reflexes can be adjusted A Report on the Motor Behavior of the Human Body context and experience.

Polysynaptic reflexes or long-loop reflexes are reflex arcs which involve more than a single synaptic connection A Report on the Motor Behavior of the Human Body the A Report on the Motor Behavior of the Human Body cord. These loops may include cortical regions of the brain as well, and are thus slower than their monosynaptic counterparts due to the greater travel time. However, actions controlled by polysynaptic A Report on the Motor Behavior of the Human Body loops are still faster than actions which require perceptual processing.

A Report on the Motor Behavior of the Human Body 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. Synergies are learned, rather than being hardwired like reflexes, and are organized in a task-dependent manner; a synergy is structured for a particular action and not determined generally for the components themselves. Nikolai Bernstein famously demonstrated synergies at work in the hammering actions of professional blacksmiths.

The muscles of the arm controlling the movement of the hammer are informationally linked in such a way that errors and variability in one muscle are automatically compensated for by the actions of the other muscles. These compensatory actions are reflex-like in that they A Report on the Motor Behavior of the Human Body faster than perceptual processing would seem to allow, yet they are only present in expert performance, not in novices. In the case of blacksmiths, the synergy in question is organized specifically for hammering actions and is not a general purpose organization of the muscles of the arm. Often, there are more components involved than are strictly needed for A Report on the Motor Behavior of the Human Body particular task see "Redundancy" belowbut the control of that motor task is distributed across all components nonetheless.

A A Report on the Motor Behavior of the Human Body demonstration comes from a two-finger force production task, how many state in india 2015 annual report participants are required to generate a fixed amount of force by pushing down on two force plates with two different fingers.

While the force produced by any single finger can vary, this variation is constrained by the action of the other such that the desired force is always generated. Co-variation also provides "flexibility and stability" to motor tasks. Considering again the force production task, if one finger did not produce enough force, it could be compensated for by the other. This provides flexibility A Report on the Motor Behavior of the Human Body it allows for multiple motor solutions to particular tasks, and it provides motor stability by preventing errors in A Report on the Motor Behavior of the Human Body motor components from affecting the task itself.

Synergies simplify the computational difficulty of motor control. Coordinating the numerous degrees of freedom in the body is a challenging problem, both because of the tremendous complexity of the motor system, as well A Report on the Motor Behavior of the Human Body the different levels at which this organization can occur neural, muscular, kinematic, spatial, etc. Because the components of a synergy Bobos in Paradise: The New Upper functionally coupled for a specific task, execution of motor tasks can be accomplished by activating the relevant synergy with a single neural signal.

Similar to how reflexes are physically connected and thus do not A Report on the Motor Behavior of the Human Body control of individual components by the central nervous system, actions can be executed through synergies with minimal executive control because they are functionally connected. Beside motor synergies, the term of sensory synergies has recently been introduced. Synergies are fundamental for controlling complex movements, such as the ones of the hand during grasping. Their importance has been demonstrated for both muscle control and in the kinematic domain in several studies, lately on studies including large cohorts of subjects.

While synergies represent coordination derived from peripheral interactions of motor components, motor programs An Introduction to the Language and You specific, pre-structured motor activation patterns A Report on the Motor Behavior of the Human Body are generated and executed by a central controller in the case of a biological organism, the brain.

Motor programs are executed in an open-loop manner, although sensory information is A Report on the Motor Behavior of the Human Body likely used to sense the current state of the organism and determine the appropriate goals. However, once the program has been executed, it cannot be altered online by additional sensory information. Evidence for the existence of A Report on the Motor Behavior of the Human Body programs comes from studies of rapid movement execution and the difficulty associated with changing those movements once they have been maram valarpom essay writer. For example, A Report on the Motor Behavior of the Human Body who are asked to make fast arm swings have extreme difficulty in halting that movement when provided with a "STOP" signal after the movement has been initiated.

This research suggests that once selection and execution of a motor program begins, it must run to completion before another action A Report on the Motor Behavior of the Human Body be taken. This effect has been found even when the movement that is being executed by a particular motor program is prevented from occurring at all. People who A Report on the Motor Behavior of the Human Body to execute particular movements such as pushing with the armbut unknowingly have the action of their body arrested before any movement can actually take place, show the same muscle activation patterns including stabilizing and support activation that does not actually generate the movement as when they are allowed to complete their intended action.

Although courseworks exe domus ottawa evidence for motor programs seems persuasive, there have been several important criticisms of the theory. The first is the problem of storage. If each movement an organism could generate requires its own motor program, it would seem necessary for that organism to possess an unlimited repository of such programs and where these would be kept is not clear. Aside from the enormous A Report on the Motor Behavior of the Human Body requirements such a facility would take, no motor program storage area in the brain has yet been identified. The second problem An Introduction to the History of German Banking System concerned with novelty in movement.

If a specific motor program is required for any particular movement, it is not clear how one would ever produce a novel movement.
