Penn Medicine News: Deciphering Hidden Code Reveals Brain Activity Penn Medicine News: Deciphering Hidden Code Reveals Brain Activity PHILADELPHIA – By combining sophisticated mathematical techniques more commonly used by spies instead of scientists with the power and versatility of functional magnetic resonance imaging (fMRI), a Penn neurologist has developed a new approach for studying the inner workings of the brain. A hidden pattern is encoded in the seemingly random order of things presented to a human subject, which the brain reveals when observed with fMRI. The research is published in the journal NeuroImage.
