'mind reading' experiment reconstructs faces people are looking at from brain scans

The machine that knows what you are thinking about: Groundbreaking mind-reading experiment reconstructs the faces people are looking at from their scans of their brains Researchers used fMRI scans for experiments Were able to tell which faces subjects were looking at Could be used by police to identify criminals from witnesses brains Could also help reconstruct dreams Believed to be most advanced 'mind reading' experiment ever carried out Scientists have used brain scanners to detect and reconstruct the faces that people are thinking of, effectively reading their minds. Researchers showed participants a series of pictures of faces and them monitored their brain activity with an fMRI scanner before reconstructing the images HOW THEY DID IT Researchers showed six subjects 300 different 'training' faces while undergoing fMRI scans. The reconstructed images were good enough for the researchers to work out which face was being looked at from a selection of 600 Working with funding from the Yale Provost’s office, Cowen and post doctoral researcher Brice Kuhl, now an assistant professor at New York University, The team showed six subjects 300 different 'training” faces while undergoing fMRI scans. spot the face: Researchers used fMRI scans to work out which faces subjects were looking at Taking that fMRI data alone, researchers used their statistical library to reconstruct the faces their subjects were viewing.
