Rapid eye movement (REM) sleep is the stage of the sleep cycle during which vivid dreaming typically takes place. This crucial sleep phase, characterized by relaxed muscles, rapid eye movements, an elevated heart rate and ...
Scientists have long speculated about the physical changes that occur in the brain when a new memory is formed. Now, research from the National Institute for Physiological Sciences (NIPS) has shed light on this intriguing ...
