BRAIN GATE
What is Brain Gate/Brain Machine Interface/Brain Computer Interface???
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.
Whenever a man forgotten about his past due to certain accidental matter or he had lost his part of his body, at that time this electrode chip can be implemented on his brain and active the man as well.
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 . The ‘Brain Gate’ device can provide paralysed or motor-impaired patients a mode of communication through the translation of thought into direct computer control.
Types of Brain Computer 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.
Researchers at the University of Pittsburgh had demonstarted on a monkey that can feed itself with a robotic arm simply by using signals from its brain.
