Brain Computer Interfaces - Term Paper Exampleentists have endlessly speculated that EEG might prove helpful for a completely different kind of purpose, which is infact another counseling of sending messages to the ace, and instructions to the outside world. Until this discovery, the control and colloquy system 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 refreshing communication and control option for individuals for whom convenient options are ineffective. It provides a way of communication and control for those wad who are disabled, for whom the normal way of communication is literally impossible.The goal of the BCI system is to listening to the brain, understand its intent, and and then to materialize that intent without the involvement of muscles. This is the reason why BCI s is also termed as mind schooling technology (Wolpa w, 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 direction 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 write down 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 map it efficiently to an electronic device. There is no doubt
