introduction
Mind to movement systemNeuro prosthetic deviceBrain 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 language of neurons

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

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

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

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

Future scope
Smaller, wireless deviceThe user will have improved limb
movementsThe user will have ability to
control devices allow breathing, bladder and bowel movements

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
