Dream-Reading Machine Helps Decode Brain Activity, Study Shows

Dreams can be decoded using a machine, a step furthering efforts to understand spontaneous brain activity, according to a study published in the journal Science.

Scientists examined three subjects’ brain activity during the early stage of sleep using functional magnetic resonance imaging, or fMRI, and repeatedly woke them up to describe their dreams, the study showed. The researchers, from the Advanced Telecommunications Research Institute and Nara Institute of Science and Technology in western Japan, found correlations between participants’ fMRI patterns and verbal accounts.
