Spinal Cord

Spinal Cord

The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

Spinal Cord: Cross-sectional Anatomy

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.

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.

Spinal Cord: Information Processing

Spinal Cord: Information Processing

The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

Enteric Nervous System: Regulation of GI Motor Activity

Enteric Nervous System: Regulation of GI Motor Activity

The Enteric Nervous System (ENS) plays a pivotal role in regulating gastrointestinal or GI motor activity. This complex network of nerves, deeply embedded within the gut wall, responds to changes in the gut environment and receives input from both the autonomic nervous system and the central nervous system. By doing so, the ENS operates various programs tailored to the body's nutritional status and needs.
During periods of fasting, the ENS initiates the migrating myoelectric complex, a...

The Spinal Cord

The Spinal Cord

The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

Area of Science:

Neuroscience
Computational Biology
Motor Control

Background:

The spinal cord contains intrinsic neural networks capable of generating rhythmic locomotor movements.
Severing the spinal cord from the brain does not abolish locomotion if excitatory drive is provided.
The precise neuronal circuitry underlying spinal locomotion remains poorly understood, hindering accurate computational modeling.

Purpose of the Study:

To review the classes of spinal neurons involved in locomotion.
To examine the patterns of interconnectivity among these neurons.
To discuss the significance of spinal circuit organization along the cord's longitudinal axis.

Main Methods:

Literature review of spinal cord neuronal classes and their connectivity.
Analysis of existing knowledge on spinal circuitry for locomotion.
Synthesis of information to identify gaps in understanding.

Main Results:

Identified diverse spinal neuron classes with incompletely understood connectivity patterns.
Highlighted reliance of computational models on untested assumptions regarding spinal networks.
Emphasized the need for a comprehensive understanding of spinal neuron interconnectivity.

Conclusions:

A definitive understanding of the spinal locomotor network requires further investigation into neuron classes and their precise connections.
Future research should focus on elucidating the specific roles and interactions of different neuron types.
Proposed analytical approaches to systematically unravel the spinal locomotor circuitry.
