Brain-computer interface (BCI) is a mechanism that enables individuals to manipulate and control computers or other technological devices by utilizing their brain activities. This technology involves receiving and analyzing brain signals, which are then transformed into commands that can be easily conveyed to intelligent devices, enabling them to perform specific operations. This investigation analyses the evolution of brain chips as brain-computer interfaces from the past to the present. Brain implants and chips serve as apparatus for interfaces, transmitting information through physical interaction with neurons in the brain. No changes in content have been made.
