1. Brain Gate-Thoughts into actions

2. introduction  Mind to movement system  Neuro prosthetic device  Brain gate is brain implant system developed by CYBER KINETICS in 2003 in conjunction with DEPARTMENT OF NEUROSCIENCE,BROWN UNIVERSITY.  Based on ability to sense,transmit,analyze and apply

3. Brain The most complex organ The CPU of human body Communication through neurons

4. Principle  Intact brain neural signals generated  These signals interpreted by the system  Alternate “BrainGate Pathway” provided

5. Components  Chip :  4-millimetre silicon chip  100 electrode sensors  Detect electrical signals  Connector:  Establishes connection between chip and converter  Mounted on the skull

6.  Converter :  Shoe box sized amplifier  Signal Optical data thro’ fiber optic cable Computer  Computer:  Translates brain activity(thro’ BCI)  Uses decoding software

7. Brain-Computer Interface (BCI)  Direct communication between brain cell and computer  There are 2 types  One way BCI  Two way BCI  Based on the position of chip, they are divided into 2 types:  Invasive BCI  Non Invasive BCI

8. Working of BCI  The working of BCI can be explained with following flow chart:

9. Advantages & Disadvantages Advantages Disadvantages  Controlling remote devices  Accessing internet  Motorized wheelchair  Control robotic arm  Expensive  Risky surgery

10. Future scope  Smaller, wireless device  The user will have improved limb movements  The user will have ability to control devices allow breathing, bladder and bowel movements

11. Conclusion  The enormity of deficits caused by paralysis is strong motivation to pursue BMI solutions  This remarkable breakthrough offers hope that people who are paralyzed will be able to live independent lives
