For many years, many research centers have been conducting intensive research to establish a direct connection between the human brain and various devices. These studies aimed at controlling computers, wheelchairs, prosthetic devices and other devices with the human brain via brain signals. This is where the term "brain-computer interface" (BCI) came from. BCI is a system of communication between the brain and computer that complement each other.  This interface allows the human body to communicate not with the neural system, but with its mental activity. The article provides information on the stages of development, current status and future prospects of the BCI. The architecture of the BCI is analyzed, methods and techniques for obtaining signals from the brain are studied, and the principle of operation of devices through these signals is presented. The experiments carried out in connection with BCI applications and the results obtained are shown. Some existing problems in this area are analyzed and shortcomings are identified for the transition of BCI from laboratory environment to real life applications. Certain proposals are made for the further development of BCI (pp.46-54).
