Dan Nemrodov and Adrian Nestor of U of T Scarborough have developed a new technique which allows us to reconstruct images that an individual perceives through the use of EEG scans. Subjects Were asked to look at images of faces while attached to an EEG to collect information on the brains activity. Once completed, researchers reconstructed the images that were represented in the subject’s brain activity!
Image reconstruction of this sort has been done before, but with and fMRI instead of an EEG. fMRI’s are useful when you want to detect activity in specific brain areas, but EEG’s have better temporal resolution and are more convenient, so this development is more accessible for practical application unlike fMRI’s.
Use of EEG scanning for reconstructing images can be useful in many situations, like communicating with people who are unable to do so verbally, or for police who wants details on suspects from eye witnesses.
Research is still being done on the applicability of this method on memory, but researchers are hopeful that these findings can help improve the forensic and legal system.
