Brain-computer interfaces (BCIs) represent a cutting-edge field at the intersection of electronics, computers, computer implants, audio equipment, and neuroscience. BCIs are devices that enable direct communication between the human brain and external electronic devices, bypassing the need for traditional user input methods such as keyboards or touchscreens. These interfaces can be non-invasive, using techniques like electroencephalography (EEG) to measure brain activity, or invasive, involving the implantation of electrode arrays directly onto the brain's surface or within its tissue. BCIs hold great promise for a wide range of applications, from assisting individuals with disabilities to enhancing human cognition and perception. They can be used to control prosthetic limbs, communicate thoughts and intentions, and even restore lost sensory functions. In this way, BCIs represent a fascinating and rapidly evolving category that bridges the gap between human biology and advanced technology.
