BRAIN & NEURON
#Brain is the center of nervous system which is present in
head, protected by the skull.
#Brain controls the whole body actions and reactions.
#Neurons are the responsive cells in nervous system that
processes and transmits information by electrochemical
signals.
#There are 100 billion neurons are available in human body
linked up with up to 10,000 synaptic connection each.
1.Brain is also considered as master of all body organs.
2.When a thorn strikes our finger we drag our hand back this thing is possible due to the neurons, which sends the brain an
information that something is hurting the finger n he should release some signals to draw back the hand.
3. In other words we can say neurons are the fine branched system present allover our body.
4.Information passes through the synaptic connections n reaches the brain which has to take the decision. It happens in less then a micro seconds.

Neurons and Nervous system
#Neurons are the constituents of Nervous system and plays the vital role in
our daily life.
#Neurons have very complex operation to perform and if it stops working
then one cannot be able to work.
#Nervous system is linked with Brain and is controlled by it. The commands
specified by the brain is carried to the various organs through them.
#A simplified and elaborated diagram has been given below:-
1.Informations passes through the axons in very rapid way. As each n every information is necessary for the brain n each information has to reach it in very less time so the information in the form of signals jumps over the axons and reaches the axon tip. The axon tip then sends the information to brain. And gets the commands from the brain in return of the information.
2. The dendrites of neuron is present in the body like root structure in the body.

Company & scientists
#Cyberkinetics is a biotech company of America which is
laid down by Nicholas Halsopulas a neuroscientist in
Chicago University.
#Tim Surgenor is the CEO of Cyberkinetics .
# The scientists who made the Braingate possible are John
Donoghue, Mijail Serruya and General Friehs of Brown
University .
1.Tim surgenor is the recent CEO of Cyberkinetics.
2. The scientists had worked day and night to make this technology come true. This had helped the ALS patients to feel better n do some sort of things in computer like us.

6. Braingate Technology
#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.

7. Clinical Trials & Experiments
#The first clinical test was conducted on Mathew Nagle on
He was the first person to use the brain computer interface to
restore functionality lost due to paralysis. He was paralysized from
neck down after being stabbed.
#Neurosurgeon Gerhard Friehs implanted the Braingate chip in his brain.
#After implantation, he was able to control a computer mouse “cursor”.
Using it he was able to press buttons that can control T.V, check
s etc.
#The observations and results of the first clinical trial was published in
the journal “NATURE”.
#Second clinical trial was conducted on a 25 years old “QUADRIPLEGIC”
Patient. After implantation he was able to switch on lights, adjust T.V
volume, change channels and read s using only his brain.
#Third experiment was conducted by the University of Pittsburgh on a
monkey who has lost a hand in accident. He was implanted with the
chip as well as the robotic hand which could able him to feed himself.
#Further more experiments are being conducted by the scientists to get
far better results.

13. Usefulness of Braingate technology
#The Braingate technology helps the physically impaired person
specially the Amyotrophic Lateral Sclerosis (ALS) patients or
the person affected from spinal injury.

14. Observation & conclusion
#The clinical trials and other experiments has shown
good results and boosted the scientists to do lot
more in this field.
#Tim Surgenor CEO, Cyberkinetic hopes to develop
Braingate in next two years to make it a wireless
device that is completely implantable and doesn’t have
a plug and making it safer and less visible.
#Scientists are predicting that human being can
interface the digital world with the Braingate
technology, if they are willing for implantation.
#Research is on to make the physically impaired
Braingate user use his own hand and leg in future.
