This document presents a seminar on neurotechnology and its applications in computing systems. It begins with an introduction and defines neurons as the basic functional units of the brain that transmit information. Neurotechnology is defined as any technology that influences understanding of the brain, thought, and higher-order brain activities. Examples of applying neurotechnology to computing are discussed, including a company called Neurotechnology. Algorithms and real-world applications are reviewed. The conclusion emphasizes the potential for neurotechnology to change the world but cautions it should not be used for harmful purposes.
