Decoded Neurofeedback A New Tool For Matrix Style Effortless Automatic Learning

Education for many serves as the primary pathway to a better more prosperous life, but what happens when emerging technology changes how we learn and acquire new skills? Imagine a world where you could learn how to play the piano, pitch the perfect fastball or operate a new piece of complex machinery by simply having the information uploaded to your brain. Researchers at Boston University and the Computational Neuroscience Laboratories in Kyoto Japan, have demonstrated the ability for an individual to; “learn high-performance tasks with little or no conscious effort”. It’s called Decoded Neurofeedback or DecNef and according to its developers it could represent a paradigm shift education and training. By leveraging the power of fMRI researchers were able to; ” use decoded functional magnetic resonance imaging  to induce brain activity patterns to match a previously known target state and thereby improve performance on visual tasks. Think of a person watching a computer screen and having his or her brain patterns modified to match those of a high-performing athlete or modified to recuperate from an accident or disease.” (Science Daily) This research many believe could lead to the development of automated learning techniques that could fundamentally change the nature of education and training.

How Thought Identification Technology May Soon “Read” Your Mind

A machine that can read your mind, once thought of as science fiction is quickly becoming a reality. It’s called thought identification and according to researchers at Carnegie Mellon University the technology to identify basic thoughts is here. The possible applications for this technology is almost limitless and it is sure to spark debates legal and ethical. How our society will adapt to this and a number of other emerging technologies is yet to be known. What is known is that this technology will become better, faster and more portable in the years to come as the force of accelerating change takes hold.

UC Berkeley Researchers Reconstruct YouTube Videos from Brain Activity

by Radford Castro of  lazytechguys.com

“Think Minority Report because this one is a trip. Now, the video you’re about to see is somewhat disturbing because what the university has accomplished is short of astounding. While the quality of the videos they recreate isn’t good at all, it’s still scary that an image can still be displayed.

How do they do this?

The study had the participants in an MRI machine for hours at a time watching YouTube videos. The data gathered by the MRI machine was used to create a computer model that matched the features of the video like colors, shapes, and movements with the brain activity.

The video was recreated by looking at slight changes in blood flow to visual areas of the brain were used to predict what was on the screen at the time. The team thinks that one day the tech could be used to broadcast imagery that plays in the mind independent from vision. You know what? Just watch it.” Source: LTG
