  • 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.
  • Brain technology

    1. 1. Braingate technology
    2. 2. INTRODUCTION•This technology is associated with a brain computerinterface chip, computer and brain.•The chip so called is, implanted in human brain inthe motor cortex region.•The chip contains an internal signal sensor andexternal processor that converts neural signals into anoutput signal or we can say thoughts are directlyconverted into computer control. This technology isbased on to sense, transmit, analysis and apply thelanguage of neurons. Braingate technology
    3. 3. •The signals generated by brain are interpreted andtranslated into cursor movement in computer screen tocontrol 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 unobtrusiveconnection between the brain of a severely disabledperson and personal computer Braingate technology
    4. 4. •Cyberkinetics is a biotech company of Americawhich is laid down by Nicholas Halsopulas aneuroscientist in Chicago University.•Tim Surgenor is the CEO of Cyberkinetics .•The scientists who made the Braingate possible areJohn Donoghue, Mijail Serruya and General Friehsof Brown University . Braingate technology
    5. 5. PRINCIPLE• The principle of operation of the BrainGate NeuralInterface System is that with intact brain function, neuralsignals are generated even though they are not sent to thearms, hands and legs.• These signals are interpreted by the System and a cursoris shown to the user on a computer screen that provides analternate "BrainGate pathway". The user can use thatcursor to control the computer, just as a mouse is used." Braingate technology
    6. 6. • The first clinical test was conducted on MathewNagle on 22.06.2004. He was the first person to usethe brain computer interface to restore functionalitylost due to paralysis. He was paralysized from neckdown after being stabbed.• Neurosurgeon Gerhard Friehs implanted theBraingate chip in his brain.• After implantation, he was able to control a computermouse “cursor”. Using it he was able to press buttonsthat can control T.V, check e-mails etc. Braingate technology
    7. 7. •Second clinical trial was conducted on a 25 years old“QUADRIPLEGIC” Patient. After implantation he wasable to switch on lights, adjust T.V volume, changechannels and read e-mails using only his brain.•Third experiment was conducted by the University ofPittsburgh on a monkey who has lost a hand inaccident.•He was implanted with the chip as well as the robotichand which could able him to feed himself.•Further more experiments are being conducted by thescientists to get far better results. Braingate technology
    8. 8. NAGLE’S STATEMENT“I cant put it into words. Its just—I use my brain. I just thought it. I said,"Cursor go up to the top right." And it did, and now I can control it all over thescreen. It will give me a sense of independence.” Braingate technology
    9. 9. Braingate technology
    10. 10. Braingate technology
    11. 11. • The Braingate technology helps the physicallyimpaired person specially the Amyotrophic LateralSclerosis (ALS) patients or the person affected fromspinal injury. Braingate technology
    12. 12. ADVANTAGES• potential to interface with a computer without weeksor months of training.• Its potential to be used in an interactive environment,where the users ability to operate the device is notaffected by their speech, eye movements or ambientnoise.• The ability to provide significantly more usefulnessand utility than other approaches by connecting directlyto the part of the brain that controls hand movement andgestures. Braingate technology
    13. 13. DISADVANTAGES• The disadvantage of the BrainGate Technology is that atthis time, while still being perfected, the switches must befrequenly adjusted which is a time consuming process.• The BrainGate Neural Interface System has not beenapproved by the FDA, but has been approved for IDEstatus, which means that it has been approved for pre-market clinical trials. There are no estimates on cost orinsurance at this time. Braingate technology
    14. 14. CONCLUSION• The clinical trials and other experiments has showngood results and boosted the scientists to do lot more inthis field.• Tim Surgenor CEO, Cyberkinetic hopes to developBraingate in next two years to make it a wireless devicethat is completely implantable and doesn’t have a plugand making it safer and less visible.• So this idea helps many patients to control theprosthetic devices of their own by simply thinking aboutthe task..
