by using power of the mind its possible turn thoughts into action
for paralyzed patients, such as turning of the tv, stereo or lights
with brain waves. brain gate technology has to do with brain mappingA
bundle of wires as thick as a coaxial cable runs from a connector in
human scalp to a refrigerator-sized cart of electronic gear. Inside
his brain, a tiny array of microelectrodes picks up the cacophony of
his neural activity; processors recognize the patterns associated
with arm motions and translate them into signals that control the
Pong paddle, draw with a cursor, operate a TV, and open email. . It
could be the next big thing. Just a minute, while looking at the
garage and the garage door went up. Seriously though, the
possibilities are endless. brain-computer interfaces can return
function to people paralyzed by injury or disease. BCI is the most
sophisticated ever tested on a human being, the culmination of two
decades of research in neural recording and decoding. A Foxborough,
Massachusetts-based company called Cyberkinetics built the system,
named BrainGate.BrainGate„¢ collects and analyzes the brainwaves of individuals with pronounced physical disabilities, turning thoughts into actions
#This technology is associated with a brain computer interface chip,
computer and brain.
#The chip so called is, implanted in human brain in the motor cortex
region.
#The chip contains an internal signal sensor and external processor
that
converts neural signals into an output signal or we can say thoughts
are directly converted into computer control.
#This technology is based on to sense, transmit, analysis and apply
the
language of neurons.
#It consist of a sensor that is implanted on the motor cortex of the
brain and a device that analyses brain signals. The signals generated
by brain are interpreted and translated into cursor movement in
computer screen to control the computer.
#The chip is a size of a Aspirin tablet of 2mmx2mm in size.
#It is a 96 hair thin electrode sensor that detects brain cell
electrical
activity.
#The chip provides a fast, reliable and unobtrusive connection
between
the brain of a severely disabled person and personal computer.
