Brain-computer interfaces

Abstract

Brain-computer interfaces (BCIs) are systems that allow communication between the brain and external devices. This field has seen significant investment since the 1970s, particularly in clinical and ergonomic applications. BCIs rely on the ability to record and interpret brain activity, using techniques like electroencephalography (EEG), which records electrical activity in the brain through electrodes placed on the scalp. EEG-based BCIs are the most developed and extensively researched type, allowing for the detection of brain states, such as attention and fatigue, and have applications in communication, rehabilitation, and cognitive augmentation. Other BCI technologies, such as brain implants, are also being explored for potential applications like drug rehabilitation and the transmission of thoughts between individuals. The field of BCIs is expected to continue growing due to advancements in signal processing, machine learning, and computing power. – AI-generated abstract.
