The central nervous system controls body posture and limb movement against disturbances. It uses global variables considering limb dynamics and neural substrates for movement control.

Area of Science:

  • Neuroscience
  • Motor Control
  • Biomechanics

Background:

  • Maintaining body posture and limb movement requires complex control mechanisms to counteract external forces.
  • Understanding the central nervous system's role in motor control is crucial for addressing movement disorders.

Purpose of the Study:

  • To review studies on central nervous system control of posture and limb movement.
  • To discuss the role of global control variables in motor control.
  • To consider neural substrates involved in kinematic and dynamic parameter control.

Main Methods:

  • Literature review of studies on motor control and central nervous system function.
  • Analysis of control variables in maintaining posture and limb movement.
  • Examination of neural substrates for kinematic and dynamic parameter regulation.

Main Results:

  • The central nervous system employs sophisticated strategies to maintain posture and limb movement against disturbing forces.
  • Global control variables, accounting for limb dynamics, are integral to motor control.
  • Distributed neural substrates contribute to the regulation of kinematic and dynamic parameters.

Conclusions:

  • Effective motor control relies on the central nervous system's ability to integrate dynamic limb information.
  • Neural control of movement is distributed, involving multiple substrates for kinematic and dynamic regulation.
  • Further research into these control mechanisms can inform therapeutic interventions for motor impairments.
