Brain⁃computer interface technology and its applications in neuroscience

Abstract

Brain ⁃ computer interface (BCI) is a cutting ⁃ edge technology of interdisciplinary integration, which has been widely used in many fields. This article introduces the four key parts of BCI technology, including signal acquisition, feature extraction, feature classification and external devices manipulation. This review introduces the application status of BCI in the medical field, we focus on the application of network science and deep learning in BCI, including extracting deeper electroencephalography (EEG) signal representations and achieving high ⁃ precision classification. Lastly, we explore the application prospects and challenges of BCI in the medical field.
