|February 23, 2011
Summary
This review compares speech and limb motor control, highlighting shared concepts and domain-specific differences in cognitive and biomechanical factors. Understanding these distinctions enhances our knowledge of motor control systems.
Area of Science:
- Neuroscience
- Biomechanics
- Cognitive Science
Background:
- Speech and limb motor control are distinct yet share underlying principles.
- Understanding their differences and similarities offers insights into motor control mechanisms.
Purpose of the Study:
- To conduct a comparative conceptual review of speech and limb motor control.
- To identify shared thinking and differing approaches between the two domains.
Main Methods:
- Conceptual review and comparative analysis.
- Examination of intrinsic vs. extrinsic variables in motor goal representation.
- Analysis of terminal postures versus entire trajectories in motor control.
Main Results:
- Speech control is cognitive and language-constrained; limb control is object-oriented.
- Key differences exist in biomechanics (soft tissue, degrees of freedom, production rates vs. inertia).
- Timing, coordination, and coarticulation are crucial in speech but less studied in limb movements.
Conclusions:
- Conceptual interchange between speech and limb motor control fields has been beneficial.
- Continued cross-domain dialogue promises further advancements in understanding motor control.

01:18Hierarchy of Motor Control
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.
01:11Direct Motor Pathways
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 the...

01:22Indirect Motor Pathways
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

01:28Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
01:13Motor Units
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.
