Brain Gate-Thoughts into actions

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

Components Chip :

4-millimetre silicon chip 100 electrode sensors Detect electrical signals

Connector:

Establishes connection between chip and converter Mounted on the skull

Converter : Shoe box sized amplifier Signal Optical data thro’ fiber optic cable Computer

Computer: Translates brain activity(thro’ BCI) Uses decoding software

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:

Advantages & Disadvantages

Advantages Disadvantages

Controlling remote devices

Accessing internetMotorized wheelchairControl robotic arm

ExpensiveRisky surgery

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
