Neural implants are devices placed in or on the brain to monitor or stimulate neural activity. They can help treat conditions like Parkinson's disease, epilepsy, and depression by delivering electrical signals to specific brain areas. These implants can also assist in restoring lost functions, such as movement or communication, for individuals with disabilities. Research in neural implants is advancing rapidly, with scientists exploring their potential for enhancing cognitive abilities and memory. Some experimental devices aim to connect the brain directly to computers, allowing for new ways to interact with technology. This field raises ethical questions about privacy and the implications of altering human cognition.
