Neuroprosthetic electrodes are crucial for restoring lost functions after nervous system injuries. This chapter reviews nerve electrode types and their biomedical applications in neuroprosthetic systems.
Area of Science:
- Biomedical Engineering
- Neuroscience
- Rehabilitation Technology
Background:
- Nervous system injuries result in significant loss of sensory, motor, and autonomic functions.
- Millions worldwide are affected, necessitating advanced solutions for functional restoration.
- Neuroprostheses and bionic systems aim to mimic or restore lost bodily functions.
Purpose of the Study:
- To provide an overview of nerve electrodes used in neuroprosthetic systems.
- To discuss the state-of-the-art biomedical applications of these electrodes.
- To explore the relationship between electrode invasiveness, selectivity, and nerve damage.
Main Methods:
- Classification of nerve electrodes based on invasiveness: extraneural, intraneural, and regenerative.
- Review of current biomedical applications in neuroprosthetic development.
- Analysis of the trade-offs between invasiveness, selectivity, and potential nerve damage.
Main Results:
- Nerve electrodes are essential for interfacing the nervous system with neuroprosthetic devices.
- Increased invasiveness can lead to higher selectivity in neural interfacing.
- The choice of electrode impacts both functional restoration and potential nerve injury.
Conclusions:
- Nerve electrodes are pivotal components in neuroprosthetic systems for restoring function.
- Understanding electrode invasiveness and selectivity is critical for effective neuroprosthetic design.
- Continued research into nerve electrodes is vital for advancing neuroprosthetic applications.

Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...
Organization of the Nervous System
The CNS, comprising the brain and spinal cord, houses billions of neurons. The brain is housed in the skull, while the spinal cord is linked to the brain through the foramen magnum of the occipital bone and is surrounded by the protective structure of the vertebral column. It is responsible for processing various...
