Brain Computer Interfaces - Term Paper Exampleentists have always speculated that EEG might conjure up helpful for a completely different kind of purpose, which is infact another way of sending messages to the brain, and instructions to the outside world. Until this discovery, the control and communication organization solely depended on the muscles and nerves. But with EEG, communication with out the use of muscles and nerves is achieved with the help of brain computer interface. Brain computer Interfaces a new communication and control preference for individuals for whom convenient options atomic number 18 ineffective. It provides a way of communication and control for those people who are disabled, for whom the normal way of communication is literally impossible.The goal of the BCI system is to listen to the brain, understand its role, and then to materialize that intent without the involvement of muscles. This is the reason why BCI s is also termed as mind reading technology (Wolpaw, R & Birbaumer, Niels p.603).The BCI system reads the Electrophysiological signals reflecting brain activity, and they are acquired from the scalp, cortical surface or from within the brain (Wolpaw, R & Birbaumer, Niels) . They are transferred to measure certain signals which help in knowing the intent of the user. These signals are converted into commands. These commands, in turn, fulfil the user intent like operating a machine, speaking something, walking in a particular flush etc.The interfaces which are Invasive are directly implanted in the brain. These are normally used in blind or paralyzed patients. The interfaces which are semi invasive are implanted inside the brain but not within the brain of an individual. Non invasive interfaces record the brain signals through a neuro-imaging procedure (Brain Computer Interfaces).Brain Computer Interfaces still have a long way to go. Researches are being conducted to understand brain functioning and to correspond it efficien tly to an electronic device. There is no doubt
