WHAT IS BRAIN GATE TECHNOLOGY ?

Brain gate is an electrode chip which can be

implemented in the brain. When it is

implemented in brain, the electrical signal

exchanged by neurons within the brain.

Those signals are sent to the brain and it

executes body movement. All the signaling

process is handled by special software. The

signal sends to the computer and then the

computer is controlled by patient.

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 .

TYPES OF BRAIN GATE 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.

HOW IT IMPLEMENTS & WORK

BRAIN GATE RESEARCH IN ANIMALS

INSERT VIDEO

ON RATS

At first, rats were implanted with BCI .

Signals recorded from the cerebral cortex of

rat to operate BCI.

ON MONKEY

Researchers at the University of Pittsburgh

had demonstrate on a monkey that can

feed Itself with a robotic arm simply by using

signals from its brain to carryout the

movement.

SOFTWARE BEHIND BRAIN GATE

The computers translate brain activity And

create the communication output using

decoding software system uses

The algorithms are written in C, JAVA and

MATLAB

CHALLENGES FACED BY BRAIN GATE

It is very expensive.

Limitation in information transform

rate. The latest technology is 20

bits/min.

Difficulty in adaptation and

learning.

FURTHER CONCERNS

Emphasis should be on improving the

information transform rate.

Stronger algorithm should be

Implemented
