BRAIN GATE SYSTEM
Presentation By

What is brain gate system?
The mind-to-movement system that allows a quadriplegic man to control a computer using only his thoughts.
INTRODUCTION
Neuroprosthetic devicePrinciple
Brain implant system developed by Bio-tech company Cyberkinetics in 2008 in conjunction with the department of Neuroscience at Brown University
Computer chip, implanted into the brain, monitors brain activity and converts the intention of the user into computer commands.
Chip uses 100 hair-thin electrodes that ‘hear’ neurons firing in specific areas of the brain.
Neuro chip
Brain Computer Interface (BCI):
The main working procedure of brain gate system.
Direct communication pathway between a brain and an external device
ANIMAL BCI RESEARCH
HUMAN BCI RESEARCH
Invasive BCIPartially Invasive BCINon Invasive BCI
INVASIVE BCI
Implanted directly into the grey matter of the brain during neurosurgery.
PARTIAL INVASIVE BCI
Implanted inside the skull but rest outside the
brain rather than within the grey matter.
PARTIAL INVASIVE BCI
Electrocorticography(ECoG):
The electrodes are embedded in a thin plastic pad that is placed above the cortex.
Light Reactive Imaging:
Implanting a laser inside the skull.
NON INVASIVE BCI
Neuroimaging technologies as interfaces are used
Signals recorded in this way have been used to power muscle implants and restore partial movement in an experimental volunteer
Produce poor signal resolution
NON INVASIVE BCI Electroencephalography(EEG) Magnetoencephalography (MEG) Hat Allows Computer Control By Thought

APPLICATIONS
Typing words by mind
A boon to the paralysed
Mathew-Nagle the first person to use the brain-computer interface to restore functionality lost due to paralysis
Controlling robots by thoughts alone
To treat congenital blindness
The idea of moving robots or prosthetic devices not by manual control has been fascinated approach. This system helps many paralysis patients to control the prosthetic devices by simply thinking about the task.
