5Question: In Neuroscience, What Does the Function of a Brain-Computer Interface (BCI) Primarily Aim to Achieve? In the rapidly evolving field of neuroscience, brain-computer interfaces (BCIs) represent one of the most transformative technological breakthroughs of the 21st century. But what is the primary function of a BCI, and why is it so crucial in modern neuroscientific research and clinical applications? A Brain-Computer Interface (BCI) is a system that enables direct communication between the brain and an external device—without relying on traditional muscle pathways. At its core, the main goal of BCI technology is to translate neural activity into actionable commands that allow individuals to control computers, prosthetics, wheelchairs, or other assistive technologies using only their thoughts. ### How BCIs Achieve This Neural Communication
