The term "brain implant" is commonly used to describe a medical device that is surgically implanted in the brain to alleviate neurological disorders. However, such implants have various synonyms, including neural implants, neuroprosthetics, cortical implants, brain chips, and brain-machine interfaces. Neural implants can be used to help paralyzed patients move their limbs, restore sight and hearing to those who have lost them, control epileptic seizures, and even treat mental health conditions like depression. These advanced medical devices are revolutionizing the way we treat neurological disorders and are opening up new possibilities for restoring lost function and improving the quality of life for those who require them.
