The ability to remember the past and imagine the future can significantly affect a person's decisions in life. Scientists refer to the brain’s ability to think about the past, present, and future as "chronesthesia," or mental time travel, although little is known about which parts of the brain are responsible for these conscious experiences. In a new study, researchers have used functional magnetic resonance imaging (fMRI) to investigate the neural correlates of mental time travel and better understand the nature of the mental time in which the metaphorical "travel" occurs.
