Brain Computer Interface (BCI) - seminar PPT

Editor's Notes

1. If a man get paralyzed, is there any way to bring him back? Is there any methods to enhance ones strengths? How to empower skills of soldiers? How artificial organs can work together with our brain signals and sensations?
2. With intact brain function, brain signals are generated even though they are not sent to the arms, hands and legs. The signals are interpreted and transmitted into cursor movements.
3. 1. Brain chip A Four millimeter square silicon chip studded with 100 hair-thin, micro electrodes is embedded in brain’s primary motor cortex. The sensors detects tiny electrical signals generated when a user imagines. 2. The Connector The signal from the brain is transmitted through the pedestal plug attached to the skull. 3. The Converter The signal travels to an amplifier where it is converted to optical data and bounced by fibre-optic cable to a computer. 4. The Computer A brain-computer interface uses electrophysiological signals to control remote devices. The Brain Computer Interface which are invasive is prerefrable. The electrodes pick up the brain’s electrical activity (at the microvolt level) and carry it into amplifiers. These amplifiers amplify the signal approximately ten thousand times and then pass the signal via an analog to digital converter to a computer for processing. The computer processes the EEG signal and uses it in order to accomplish tasks such as communication and environmental control.
