During the two-hour fMRI scan conducted three days ago, researchers tested Sharon’s response to various stimuli: family pictures, a recording of his son’s voice, and human touch. They said they were surprised to discover significant activity in relevant parts of his brain in response to all tests. “These results point to mental processing of sensory information,” Soroka reported. Sharon was transferred to Soroka from Sheba Medical Center for the purpose of the neurological tests.
