Summary
This study introduces a new noninvasive therapy for spinal cord injury using magnetic stimulation and piezoelectric nanomaterials. This approach promotes nerve regeneration and improves motor function without requiring implants.
Area of Science:
- Biomedical Engineering
- Neuroscience
- Regenerative Medicine
Background:
- Intracorporeal electrical stimulation shows promise for spinal cord injury (SCI) recovery.
- Conventional methods face challenges like infection risks and external power dependency.
- Improving stimulation precision and noninvasiveness is crucial for SCI treatment.
Purpose of the Study:
- To develop a novel, noninvasive therapeutic strategy for SCI.
- To integrate extracorporeal magnetic stimulation with piezoelectric nanomaterials for precise electrical stimulation.
- To overcome limitations of current intracorporeal stimulation methods.
Main Methods:
- Developed energy-storing, sustained-release piezoelectric nanocapacitors.
- Integrated these with extracorporeal trans-spinal magnetic stimulation.
- Investigated current conduction across the dura mater and its effects on neural tissue.
Main Results:
- Piezoelectric nanocapacitors induced localized current conduction across the dura mater.
- Demonstrated effective corticospinal tract axonal regeneration distal to the SCI site.
- Showed restoration of functional neural connectivity and improved lower limb motor performance.
Conclusions:
- The novel approach offers precise, noninvasive electrical stimulation for SCI.
- Magnetically responsive piezoelectric nanocapacitors enable implant-free, long-term neuromodulation.
- This strategy establishes a new paradigm for extracorporeal neuromodulation in SCI therapy.

01:26Spinal Cord
1.6K
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.

01:54The Spinal Cord
31.6K
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.

01:10Spinal Cord: Information Processing
3.3K
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...

5.4K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

4.4K
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.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
