Recently, one of the latest technologies introduced in the computer science field is the mind reading computer. This is a new computer program that has ability to decode the thoughts of people almost in real time. The new research shows that this decoding happens within a few milliseconds of someone after seeing the image. The researchers also predict that the people are seeing depend on the electrical signals coming from the electrodes implanted in their brain. The new results explained that this new technology application can greatly helps people for those who cannot speak or having trouble in communicating and expressing thoughts with others.
Rajesh Rao, a neuroscientists at the University of Washington in Seattle said that clinically, this technology has built a communication mechanism for the patients who have had paralyzed or stroke that are completely locked in. Over the past few years, many scientists have made the tremendous studies about this decoding human thought. According to the study conducted in 2011, the researchers can translate the brain waves into the movie clips for people who were watching at that time. After that, the two scientists in 2014 can be transmitted the human thoughts to each other by using a brain to brain link. However, these studies have been shown that the computers can see what the people are dreaming about this and use only their activities of the brain.
Later on, Rao and his colleagues do further research in this effort. They asked seven people with extreme epilepsy who already had undergone this surgery to implant the electrodes into the temporal lobes, if the thoughts in their mind can be decoded. Here, the temporal lobe is the brain region, which is responsible to process the sensory input such as recognizing and visualizing the objects in which a person sees. During this researching process, the Rao and their colleagues can be watched the system screen, where many images are briefly flickered by.
On the other hand, the electrodes were hooked up into this powerful computer program that can be analyzed the brain signals minimum 1, 000 times per second. They also find out what the brain signals look like, especially when someone has viewed an image. The first two-third of images shows that the system program got a label and tells that this is what the brain signal looks like when someone view an image. And the remaining one-third of pictures, the system was able to predict with 98% accuracy and tells what the personal actually saw. However, the system can be accomplished this task within 20 milliseconds by scanning a person instantly.
When the people were looking at the faces, it has been turned out the different neurons fired. In this mind reading computer application, the computer usually required two forms of brain signals to decode the images such as a broadband spectral change and an event related potential. This occasion is related to the prospective characteristic impale in the brain cell firing, which occurs when the brain react to every stimulus.
On the other hand, the broadband spectral change is normally detected by the electrodes, where the entire change in power across the region of the brain. But this scientist looks at single neurons and several studies give a more global image at the larger network of neuron levels. These will shows that how the people are awake and paying attention to the difficult visual object. This new technology like mind reading computer sounds like the great science fiction. These computers can be able to decode the human thoughts into the written words or actual speech without even telling a single word.
Once you sits in front of the computer, it will starts read your minds and improve the capabilities of current speech interfaces with devices. However, this is an amazing technology application for those who feel difficulties in speech. When it comes to brain, this technology cannot be easily made commercially available because one size does not exactly fit for all. Transmission of phonetic data by the brain waves is so sensitive in which every brain need to be assessed individually. Thus, this new method can detect the electromagnetic activity of neurons responding to the speech.
