A brain-computer interface (BCI) enables humans to control computers and devices using thoughts by detecting electrical signals in the brain with electrodes. The BCI system includes signal detection, processing, and output development, with both invasive and non-invasive methods available. Applications of BCI range from communication aids for individuals with disabilities to enhancements like neuroprosthetics and potential mind control technologies.

- 2. Introduction A brain computer is a technology which allows a human to control a computer, peripheral or electronic device with thought. It does so by using electrodes to detect to electric signal in the brain which are send to a computer. The computer then translate this electric signal into data which is used to control a computer or a device linked to a computer.
- 3. Basic block diagram of BCI system incorporating signal detection , processing and developing.
- 4. BCI WORKING
- 8. Basic mechanism 1. Wires from each electrode transmit their measurement to a computer. 2. The electrode measure minute difference in the voltage between neuron. 3. The signal is then amplified and filtered. 4. The computer produces a graph showing the reading from each electrode.

- 12. Non-invasive BCI
- 15. -For people with certain disabilities ( paraplegia, amyotrophia, …) BCI might be the only of communication. -Human enhancement: . cybernetic organism . Brainwave synchronization . Exocortex (intelligence booster) -Human manipulation: . Mind control . “Neurohaking” unwanted reading information from brain -neuroprosthetics: -surgically implanted devices used as replacement for damaged neuron. -Develop intelligence relaxation device. -provide additional channel of control in computer games. -”Google search” through brain
