Jack Gallant’s lab uses cutting edge neuroimaging methods and computational models to study how the human brain encodes and maps sensory and cognitive information. Gallant created a “brain decoder” which turns brain data from an fMRI scanner into dynamic visuals on a computer screen, a method that allows to show representations of images and videos seen by a person under the scanner. This ground-breaking development paves the way for the reproduction of internal images: language, thoughts, memories, even dreams, and provides new insights into the way the brain processes information.
