Neuroscientists at Canada’s University of Toronto Scarborough are using A.I. for reconstructing images based on brain perception using data gathered by electroencephalography.
During the research, the participants were connected to an electroencephalogram, and various faces were displayed on the screen. Meanwhile their brain activity was filmed, and then analyzed using algorithms for machine learning. The marked brain activity turned into images that the examinees see in their head.
While this isn’t the first time that A.I. has been used to read people’s minds, it’s the first time this has been achieved using EEG data. Previous studies involved fMRI technology, which measures brain activity by detecting changes in its blood flow, posted Digital Trends.
The researchers found that the brain needed 170 milliseconds to remember the person we see in front of us. The technology could potentially be used by law enforcement for creating more accurate eyewitness reports about a potential suspect’s likeness.
