Hierarchy of Motor Control

Hierarchy 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.

Major Somatic Sensory Pathways

Major 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...

Motor Unit Stimulation

Motor Unit Stimulation

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...

Understanding the Self

Understanding the Self

The self is a central aspect of human identity, encompassing an individual’s beliefs, emotions, perceptions, and experiences. It is a cognitive and psychological construct that enables individuals to interpret their traits and behaviors, influencing how they perceive themselves and interact with the world. While personality consists of stable and enduring characteristics, the self is shaped by self-perception and social experiences. This distinction highlights the dynamic nature of the self,...

Indirect Motor Pathways

Indirect 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...

Direct Motor Pathways

Direct 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...

Summary

This summary is machine-generated.

The body self-advantage, a better performance recognizing one's own body, emerges from implicit motor representations. Explicit self-body recognition tasks do not show this advantage, suggesting distinct processing pathways for implicit and explicit self-recognition.

Area of Science:

Cognitive Neuroscience
Body Representation
Self-Recognition

Background:

Humans implicitly recognize their own body, exhibiting a self-advantage in visual matching tasks.
This self-advantage is characterized by superior performance with self-related body parts compared to others'.

Purpose of the Study:

To investigate if the body self-advantage is dependent on motor representations of the body.
To explore whether the self-advantage differs between implicit and explicit self-body processing.

Main Methods:

Participants performed a hand laterality judgment task involving self and others' hands, requiring sensory-motor simulation.
An explicit self-body recognition task was also administered to assess conscious self-processing.

Main Results:

The self-advantage was observed during the implicit laterality judgment task.
No self-advantage was found during the explicit self-body recognition task.

Conclusions:

Implicit and explicit recognition of the bodily self are distinct processes.
The body self-advantage appears to rely on implicit, motor-based representations of the self.
