Brain-computer interface (BCI) is a collaboration between a brain and a device that enables signals from the brain to direct some external activity, such as control of a cursor or a prosthetic limb. The interface enables a direct communications pathway between the brain and the object to be controlled. In the case of cursor control

16. DARPA stands for ”Defense Advanced Research Projects Agency”

17. The papers published after this research also mark the first appearance of the expression brain–computer interface in scientific literature.

21. BCI Works on EEG technology

23. Our mind produce various waves, Scientists can detect those signals, interpret what they mean and use them to direct a device of some kind.

24. the recording of electrical activity along the scalp produced by the firing of neurons within the brain.

25. Neurons Means

30. Theta is the frequency range from 4 Hz to 7 Hz. Theta is seen normally in young children. It may be seen in drowsiness or arousal in older children and adults; it can also be seen in meditation.

31. Alpha is the frequency range from 8 Hzto 12 Hz. Hans Berger named the first rhythmic EEG activity he saw, the "alpha wave." This is activity in the 8–12 Hz range seen in the posterior regions of the head on both sides, being higher in amplitude on the dominant side. It is brought out by closing the eyes and by relaxation.

36. BCI Applications: This Image Shows Artificial Eye by using BCI technology This Image Shows BCI Device which is use for play Games by Brain

37. BCI applications: Honda’s Brain Machine interface controlling robots by thoughts. This is The BCI ear chip

38. BCI research…

40. Monkeys have navigated computer cursors on screen and commanded robotic arms to perform simple tasks simply by thinking about the task and without any motor output.

42. Advantages of BCI…

44. A hearing impaired person can hear sound..

45. A blind person can see everything…

46. A person can play games by his/her brain waves…

47. A person who don’t have hand or leg can do the work by robotic hand or leg…

49. Future developments Early BCI: signal splicing into human sensory nerve pathways, most importantly the visual nerve. Mid-term BCI: more direct links into the brain with the ability to read certain thoughts and copy a wide range of data and information into various parts of the brain. Final BCI: direct control over the activities of all individual neurons by means of nanorobots. Arbitrary read/write access to the whole brain. The line between the mind and the computer is blurred. Partial or full uploading is possible and inevitable.
