Neurotechnology has the potential to revolutionize our understanding of the brain, improve diagnostics and treatments for neurological and psychiatric disorders, and enhance human capabilities. Neurotechnology refers to a broad field of science and technology that focuses on understanding, manipulating, and interfacing with the nervous system. Ongoing research and advancements in neurotechnology hold great promise for the future of brain research, healthcare, and human-machine interactions. Neurotechnology combines knowledge and techniques from neuroscience, engineering, computer science, and other related disciplines to develop tools, devices, and methods for studying and modulating the brain and nervous system. Some of the main applications of human neurotechnology are the closely-related fields of BCI, neuroprosthetics, and DBS.
