2. CONTENTS HISTORY WHAT IS BRAIN GATE OBJECTIVE OF BRAIN GATE TYPES OF BRAIN GATE PRINCIPLES OF BRAIN GATE IMPLEMENTATION APPLICATIONS

3. History of Brain Gate… Brain gate was developed by the bio-tech company Cyberkinetics in 2003 in conjunction with the Department of Neuroscience at Brown University.

4. What is Brain Gate? Brain gate is an electrode chip which can be implemented in the brain. Whenever a man forgotten about his past due to certain accidental matter

5. Objective of Brain Gate !!!! The goal of the Brain Gate program is to develop a fast and reliable connection between the brain of a severely disabled person and a personal computer. The ‘Brain Gate’ device can provide paralysed or motor-impaired patients a mode of communication through the translation of thought into direct computer control.

6. Types of Brain Computer Interface(BCI): One way BCI Computers either accept commands from the brain or send signals to it. Two way BCI Allow brains and external devices to exchange information in both directions.

7. Brain Gate Research in animals: At first, rats were implanted with BCI. Signals recorded from the cerebral cortex of rat to operate BCI to carry out the movement.

8. Stage 2 Using only its mind the monkey was able to control a cursor on a computer monitor via Brain Gate.

9. PRINCIPLE: The system consists of a sensor that is implanted on the motor cortex of the brain (Pedestal) and a Brain Gate Neural Interface Device that analyzes the brain signal.

10. HOW IT IMPLEMENTS ?

11. This is one of electrode implemented in brain. Individual electrodes are 1-mm long and spaced 400m apart, in a 10x10 grid. The electrical signal exchanged by neurons within brain. Those signals are sent when the brain executes a body movement

12. APPLICATIONS In multimedia communication. In evaluation of spike detection algorithms. As a brain controlled switch for asynchronous control.

13. conclusion The results are spectacular and almost unbelievable. Finally BRAIN GATE has proved to be a boon for paralyzed patient.
