Elettroencefalogramma, EEG Che cos'è L'elettroencefalogramma, comunemente detto EEG non è altro che la misurazione dell'attività elettrica del cervello, che a sua volta è la somma dell'attività elettrica di ogni neurone. Siccome il voltaggio di questa attivitò elettrica è molto piccolo deve essere amplificata un milione di volte per essere misurata e registrata con degli elettrodi applicati sulla testa. Questo segnale elettrico viene inviato all'elettroencefalografo per essere trascritto su della carta che scorre ad una velocità costante per ottenerne un tracciato. Con questo esame si controlla anche la reattività che si ha ad opportuni stimoli come possono essere apertura degli occhi, stimolazione luminosa, rumori, stimoli tattili e altri. Come si svolge E un esame del tutto innocuo, ne doloroso ne fastidioso, viene fatto sia in ospedale che in ambulatorio. Quando si fa e perché viene utilizzata Torna indietro alla lista degli esami
MIT creates glucose fuel cell to power implanted brain-computer interfaces Neuroengineers at MIT have created a implantable fuel cell that generates electricity from the glucose present in the cerebrospinal fluid that flows around your brain and spinal cord. In theory, this fuel cell could eventually drive low-power sensors and computers that decode your brain activity to interface with prosthetic limbs. The glucose-powered fuel cell is crafted out of silicon and platinum, using standard semiconductor fabrication processes. The platinum acts as a catalyst, stripping electrons from glucose molecules, similar to how aerobic animal cells (such as our own) strip electrons from glucose with enzymes and oxygen. The glucose fuel cell products hundreds of microwatts (i.e. tenths of a milliwatt), which is a surprisingly large amount — it’s comparable to the solar cell on a calculator, for example. This should be more than enough power to drive complex computers — or perhaps more interestingly, trigger clusters of neurons in the brain.
A bionic prosthetic eye that speaks the language of your brain On the grand scale of things, we know so very little about the brain. Our thick-headedness isn’t quite cosmological in scale — we really do know almost nothing about the universe beyond Earth — but, when it comes down to it, the brain is virtually a black box. We know that stimuli goes in, usually through one of our senses, and motor neurons come out, but that’s about it. Take prosthetic arms, for example: We don’t have a clue about the calculations that occur in the brain to trigger arm muscle motor neurons, but that doesn’t stop us from slapping some electrodes onto a subject’s bicep muscles and measuring the electric pulses that occur when you tell him to “think about moving your arm.” Now, reading the brain’s output (as in a prosthetic arm) is one thing, but feeding data into the brain is something else entirely — and understanding the signals that travel from the retina, through the optic nerve, to the brain is really about as bleeding edge as it gets.
Paralyzed woman controls robotic arm, sips coffee Performing even a simple movement is a rather complicated process. First, the brain has to signal its intent to perform an action, which then gets translated into the specific motions that are required to achieve that intention. Those motions require a series of muscle contractions; the signals for these need to be sent out of the brain, through the spinal cord, and to the appropriate destination. For most people who suffer from paralysis, it's really these later steps that are affected—most of the setup can still go on in the brain, but damage keeps the signals from making their way to the muscles. If there were a way to eavesdrop on the brain, it might be possible to identify an individual's intent and translate that into some form of useful action. This may sound like science fiction, but significant progress has been made in the area. Now, we've taken the next big step. For the first task, they were asked to grasp a rubber ball attached to a stand that was easy to topple over.
Can You Make Money With Your Idea or Invention? Innovative ideas are essential to business progress. It is very difficult, however, for innovators to get the kind of financial and management support they need to realize their ideas. This publication, aimed at idea people, inventors, and innovative owner-managers of small companies, describes the tests every idea must pass before it makes money. You've Got an Idea? Great! So, you've had an idea for an invention or an innovative way of doing something that will boost productivity, put more people to work, and make lots of money for you and anyone who backs you? You are another of those individuals on whom progress has always depended. Owner-managers who have started companies on new ideas know first hand about the innovation process. You've Got an Idea? In the first place, the chances that you are the first to come up with a particular innovation are somewhere between slim and none. Why is it so hard to find backers for your brainchildren? Can You Exploit Your Idea? Is There any Hope? 1.
Spy on your brain and heart with Arduino EEG Have you always wanted to monitor your brains signals, but didn’t have the money or expertise for an expensive setup? I caught up yesterday with Jacob Shiach about the Arduino EEG Project, which I first heard at the Open Science Summit in Berkeley, CA back in July. Here’s what Jacob had to say: From an outside view, it probably looks like a torture scene from a Bond flick. Forrest is sitting there with electric wires tied to metal washers duct-taped to the side of his head. You can check out more info about the Arduino EEG on Jacob’s Kickstarter page If you have a cool science project, want to test if your food is genetically modified, or learn more about your DNA, comment on this post!

[Neuroimage. 2011 Idaho Observer: The "Current" state of Mind Control From the January 2007 Idaho Observer: The "Current" state of Mind Control by Hari Heath Mind control can be many things. For good or ill, mind control is the act of causing the mind to function according to a desired outcome. In the history of human governance, almost everything has been tried to bring the will of the people in line with the will of the governing class. Ultimately in this age, the goal of upper echelon government operators is to control the mind and achieve "consent of the governed." New technology now offers tools to bend the will and the consequences for humanity are as far-reaching and serious as the use of the atomic bomb. The recently released book, Controlling the Human Mind: The Technologies of Political Control or Tools for Peak Performance, by Dr. What it reveals is shocking enough, but what is most shocking is what it doesn't reveal.

BrainPort® V100 The BrainPort V100 is a non-surgical assistive device intended for orientation, mobility, object identification, and spot reading by individuals who are blind with no useful vision. It translates digital information from a video camera into gentle electrical stimulation patterns on the surface of the tongue. Users feel moving bubble-like patterns on their tongue which they learn to interpret as the shape, size, location and motion of objects in their environment. The BrainPort V100 is intended to augment rather than replace other assistive technologies such as the white cane or dog guide. The BrainPort V100 device is an Investigational Device and its use remains limited by U.S.
Assembling the Arduino EEG Circult - chipstein Do this on a humid day. If it’s a crisp dry spring or fall day, use a ground strap. The amplifiers require a neutral reference, or floating ground, halfway between the Arduino’s 5V positive and ground supplies. Next wire up the other 3130, which is the high-gain amplifier. Finally, install and wire up the AD 620. The two low-pass filter segments are helpful for EEG, but if you don't need it, leave off the capacitor marked with *.
