Neuroprosthetics, also known as neural prostheses, are artificial devices designed to restore lost motor or sensory function. They typically work by interfacing with the nervous system to bypass damaged pathways or to replace the function of a missing organ. This field combines neuroscience, engineering, and medicine to create solutions for individuals with conditions such as paralysis, blindness, deafness, and limb loss.

The core principle behind neuroprosthetics is their ability to stimulate or record neural activity. For example, cochlear implants directly stimulate the auditory nerve, bypassing a damaged inner ear and allowing individuals with severe hearing loss to perceive sound. Similarly, retinal implants can restore partial vision to people with certain types of blindness by stimulating the remaining healthy cells in the retina.

In the realm of motor function, neuroprosthetics can enable movement. Functional electrical stimulation (FES) can be used to activate paralyzed muscles, allowing individuals to perform actions like grasping objects or standing. More advanced systems involve brain-computer interfaces (BCIs) that translate brain signals into commands for external devices, such as robotic limbs or wheelchairs. These BCIs can be invasive, requiring surgically implanted electrodes, or non-invasive, using sensors placed on the scalp.

The development of neuroprosthetics is an ongoing area of research, with continuous advancements in materials, miniaturization, and understanding of neural pathways. The ultimate goal is to create devices that are seamlessly integrated with the body, providing a natural restoration of function and improving the quality of life for those affected by neurological disorders or injuries.
