Brain–Computer Interface (BCI) technology represents a critical convergence of neuroscience and engineering, enabling direct communication between the human brain and external devices. Since its conceptualization by Jacques Vidal in 1973, BCIs have evolved into sophisticated systems with applications spanning neuroprosthetics, rehabilitation, communication, gaming, education, and mental health. This review consolidates contemporary literature to examine the fundamental architecture of BCI systems, including signal acquisition, signal processing, and application layers. Current advances in non-invasive and invasive techniques, emerging signal-processing methodologies, and real-world implementations are discussed alongside ethical, safety, and accessibility challenges. The article concludes by outlining future directions necessary for the responsible and scalable integration of BCIs into healthcare and society.
