Which technology refers to devices that interface with the brain and nervous system to treat neurological disorders and enable control of external devices by thought?

• A. Neural Implants
• B. Blockchain
• C. Digital Twins
• D. Big Data Analytics

Answer: (A)

Neural implants are devices that interface with the brain and nervous system to treat neurological disorders and enable control of external devices by thought. They can include deep brain stimulation systems that help manage symptoms of Parkinson’s disease, as well as brain–computer interfaces that translate neural signals into commands to control prosthetics or computers. These devices either stimulate targeted brain regions or record neural activity to modulate or interpret signals for therapeutic benefit or assistive control. In contrast, blockchain focuses on secure distributed ledgers, digital twins are virtual models of physical systems for simulation, and big data analytics analyzes large datasets for patterns and insights. None of these directly connect to the brain to treat disorders or enable thought-driven control of external devices. This is what neural implants do.
