Summary
The adult central nervous system (CNS) exhibits remarkable plasticity after injury, involving both neuronal and non-neuronal cells. Understanding these cellular interactions is key to developing effective CNS injury therapies.
Area of Science:
- Neuroscience
- Cell Biology
- Regenerative Medicine
Background:
- The traditional view of a rigid central nervous system (CNS) has been replaced by the understanding of its adaptability.
- Adult CNS plasticity allows functional reorganization in response to environmental changes or CNS damage, such as trauma.
Purpose of the Study:
- To discuss cellular responses following spinal cord injury (SCI) that demonstrate plasticity.
- To highlight the roles of both neuronal and non-neuronal cells in CNS repair after injury.
Main Methods:
- Review of cellular responses at the lesion site and other CNS levels after SCI.
- Examination of morphological, fate, and biochemical changes in astrocytes and neural precursor cells.
Main Results:
- Plastic responses involve not only neurons but also non-neuronal cells like astrocytes and neural precursors.
- These cellular responses interact to remodel tissue and aid in motor function recovery.
Conclusions:
- Understanding the interplay of cellular responses is crucial for targeted therapeutic manipulation.
- This knowledge is fundamental for developing effective treatments for CNS injuries.

01:14Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
01:10Spinal 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...

01:15Neurogenesis and Regeneration of Nervous Tissue
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
