New Method Allows Scientists to Read Letters in a Person's Brain Scan

-
It's not exactly "mind reading," per se, but a team of researchers have developed a method through which they are able to determine what letter a person is looking at based on a scan of their brain.


Published in the journal Neuroimage, the study includes using an fMRI to scan a person's brain while he or she views a specific image. An fMRI works by determining where in the brain blood is flowing most and has long been used in research designed to determine which brain areas are most active while a person performs a given task.

Computers that learn from experience and adapt to a novel situation are now set to change the face of Artificial Intelligence. The commercial version of a new kind of 'neuromorphic processor' that learns from its own mistake is about to enter the markets in 2014, according to New York Times. The new technology could do away with hours of programming and even make 'computer crashes' obsolete, tolerating minor errors. The new kind of computing is based on biological systems. These new artificial neural networks could advance facial recognition that is currently in its infancy stage. The brain doesn't crash if it finds a novel idea. It forms new neural connections and interprets the signals as best as it can. The new computer chip works similarly and according to NYT, these chips are already in use in few large tech companies. "We're moving from engineering computing systems to something that has many of the characteristics of biological computing,...
