As the power of modern computer grows alongside our understanding of the human brain, we move even closer to making some pretty spectacular science fiction into reality. Imagine transmitting signals directly to someone's brain that would allow them to see, hear or feel specific sensory inputs (in short we can make any blind person watch, deaf person hear). Consider the potential to manipulate computers or machinery with nothing more than a thought. It isn't about convenience for severely disabled people; development of a brain-computer interface (BCI) could be the most important technological breakthrough in decades. In this seminars, we'll learn all about how BCIs work, their limitations and where they could be headed in the future. One of the most exciting areas of BCI research is the development of devices that can be controlled by thoughts. Some of the applications of this technology may seem frivolous, such as the ability to control a video game by thought. If you think a remote control is convenient, imagine changing channels with your mind. However, there's a bigger picture, devices that would allow severely disabled people to function independently. For a quadriplegic, something as basic as controlling a computer cursor via mental commands would represent a revolutionary improvement in quality of life.

i need more explain and diagrams..........

hi
please go through the following thread for more details on 'brain Computer Interface'

Thank you for providing link.It will be helpful to know more about 'brain Computer interface'. It's interesting topic.

There are other means of reading brain activity than direct neural contact via pins. The first and most common is electroencephalography (EEG) where electrodes are placed against the scalp are used to pick up brain signals. However, this approach is not nearly as accurate as direct neural contact and can only pickup blurry, weak readings. The other, much newer, and much more accurate non-invasive technology is magnetoencephalography (MEG) but is also more equipment intensive. Using MEG requires a room filled with super-conducting magnets and giant super-cooling helium tanks surrounded by shielded walls. This technology, while providing the speed and accuracy needed for a successful non-invasive BMI, will require significant improvement of technology in order to be realistic for everday use.

Thanks for that information on MEG.Brain Gate is a very related topic, whose report can be got from:

please can you help me with comprehensive pratical project,and explaination of how it function

brain–computer interface (BCI), sometimes called a direct neural interface or a brain–machine interface (BMI), is a direct communication pathway between the brain and an external device . BCIs usually connect the brain (or nervous system) with a computer system
there is are some more practical explanation you can read from this pages
