Hierarchy of Motor Control01:18

Hierarchy of Motor Control

6.0K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Motor Units00:46

Motor Units

61.8K
A motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.

Motor Units

7.5K
The motor unit is a fundamental component of the neuromuscular system and plays a crucial role in coordinating muscle contractions. It consists of a somatic motor neuron, which connects and controls multiple skeletal muscle fibers, forming a single functional segment. The axon of the motor neuron branches out and establishes synaptic connections known as neuromuscular junctions with individual muscle fibers within the motor unit.
Motor units come in different sizes, with smaller units...

Motor Unit Stimulation01:20

Motor Unit Stimulation

3.6K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Direct Motor Pathways01:11

Direct Motor Pathways

4.2K
The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and...

Control System Problem01:21

Control System Problem

414
In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

Area of Science:

  • Developmental neuroscience
  • Motor control
  • Human movement science

Background:

  • Motor control relies on anticipatory (feedforward) and online (feedback) processing.
  • Understanding the developmental trajectory of these systems in children is crucial.

Purpose of the Study:

  • To investigate the developmental progression of feedback and feedforward motor control in children aged 5-10 years.
  • To utilize a simple, ecologically relevant task to assess motor control development.

Main Methods:

  • Employed a reach-to-displace paradigm with manipulated object weights.
  • Manipulated object weight predictability to differentiate between anticipatory and online control.
  • Analyzed movement kinematics to quantify motor control strategies.

Main Results:

  • Children as young as 5 years demonstrated anticipatory abilities regarding object weight.
  • Adequate anticipatory control emerged around 7 years of age.
  • Online correction abilities were less developed compared to anticipatory control in this age group.

Conclusions:

  • The study elucidates the developmental timeline of anticipatory and online motor control in children.
  • The findings suggest a developmental shift towards more refined anticipatory mechanisms.
  • This paradigm offers a valuable tool for assessing motor control development and identifying atypical patterns.
