Researchers use functional MRI scans to perform brain decoding

At UCLA's Laboratory of Integrative Neuroimaging Technology, researchers use functional MRI brain scans to observe brain signal changes that take place during mental activity. They then employ computerized machine learning (ML) methods to study these patterns and identify the cognitive state - or sometimes the thought process - of human subjects. The technique is called "brain reading" or "brain decoding."
