Approximately 65% of the neurons in the pre-motor cortex are responsible for conditional "closed-loop" motor tasks. In experimentation using monkeys, when they were trained to reach in different directions, depending on the specified visual cue, the approximately coordinated lateral pre-motor neurons began to fire at the appearance of that ...
Judge Dredd: The Mega Collection was a British fortnightly partwork collection of hardback books published by Hachette Partworks. The series is made up of 90 volumes which contain thematic collections of stories about 2000 AD’s Judge Dredd and related characters, [1] as well as bonus material including previously unpublished art.

Closed loop control [24]: 186 is a feedback based mechanism of motor control, where any act on the environment creates some sort of change that affects future performance through feedback. Closed loop motor control is best suited to continuously controlled actions, but does not work quickly enough for ballistic actions.
Sensory-motor coupling is the coupling or integration of the sensory system and motor system. Sensorimotor integration is not a static process. For a given stimulus, ...
Any newly formed motor skill, such as learning to play a musical instrument or adjusting one's running stride, is subject to a consolidation period. The time course of this period during which new motor skills are susceptible to disruption appears to be on the order of a few hours. [1] [2]
Though this theory represented an important leap forward in motor learning research, [1] one weakness in Adams’ closed-loop theory was the requirement of 1-to-1 mapping between stored states (motor programs) and movements to be made. This presented an issue related to the storage capacity of the central nervous system; a vast array of ...
The goal of motor skill is to optimize the ability to perform the skill at the rate of success, precision, and to reduce the energy consumption required for performance. Performance is an act of executing a motor skill or task. Continuous practice of a specific motor skill will result in a greatly improved performance, which leads to motor ...
Proprioceptive feedback is also linked to motor deficits in Parkinson's disease and cerebral palsy. People with cerebral palsy often suffer from spasticity due to hyperreflexia. [13] A common clinical test of spasticity is the pendulum test, in which the subject remains seated and the relaxed leg is dropped from horizontal.
