Neuroengineering is an interdisciplinary field that combines principles from neuroscience, engineering, and computer science to develop technologies that interface with the nervous system. This can include creating devices that help restore lost functions, such as prosthetic limbs controlled by brain signals or brain-computer interfaces that allow communication for individuals with disabilities. Researchers in neuroengineering work on various applications, including neural implants for treating conditions like epilepsy and neuroprosthetics that assist with movement. The goal is to enhance our understanding of the brain and improve the quality of life for people with neurological disorders or injuries.
