Summary
Locomotion relies on automatic muscle tone and postural adjustments controlled by the brainstem and spinal cord. Disruptions in forebrain input to these areas can cause locomotor control disorders.
Area of Science:
- Neuroscience
- Motor Control
- Physiology
Context:
- Locomotion is a fundamental animal behavior.
- Goal-directed movement involves complex neural coordination.
- The brainstem and spinal cord are central to motor control.
Purpose:
- To review the role of the brainstem and spinal cord in controlling postural muscle tone and generating locomotor rhythms.
- To discuss how forebrain input influences these brainstem-spinal cord mechanisms.
- To explore the link between disrupted neural convergence and locomotor disorders.
Summary:
- The brainstem and spinal cord house essential mechanisms for controlling postural muscle tone and generating locomotor rhythms.
- Forebrain structures (cerebral cortex, basal ganglia, limbic-hypothalamic systems) and the cerebellum project to the brainstem-spinal cord to modulate locomotion.
- Abnormalities in these projections contribute to the pathogenesis of disturbances in locomotor control.
Impact:
- Provides insights into the neural basis of locomotion and postural control.
- Highlights the importance of the brainstem and spinal cord in motor function.
- Offers a framework for understanding neurological conditions affecting movement.

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.
Brainstem
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

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...

Brainstem: Control Centers of Medulla
The medulla oblongata is a crucial part of the brainstem responsible for controlling various autonomic and involuntary functions. It contains several nuclei, including the olivary, cuneate, gracile, and solitary nuclei.
Olivary Nucleus
The olivary nucleus, or inferior olivary nucleus, is located within the ventrolateral part of the medulla oblongata. It is primarily involved in motor coordination and motor learning. The olivary nucleus receives input from the spinal cord, cerebellum, and motor...

Physiology of Respiration II: Neurogenic Control of Respiration
The neurogenic control of respiration coordinates various neural networks and pathways to regulate breathing rate and depth, meeting the body's oxygen and carbon dioxide exchange requirements. This system adapts to physiological and environmental conditions, ensuring optimal breathing patterns.
Central Control
The brainstem is the primary site of central control, hosting respiratory centers:

Spinal Cord: Cross-sectional Anatomy
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
