REM- rapid eye movement

Back 6

recurring sleep stage during which vivd dreams commonly occur. also known as paradoxical sleep, because the muscles are relaxed for minor twitches but other body systems are active

a view of the brain activity showing where a radioactive form of glucose goes while the brain performs a given task

a technique for revealing bloodflow and therefore brain activity by comparing successive MRI scans fMRI scans show brain function

a technique that uses magnetic fields and radio waves to produce computer generated images of soft tissue - MRI scans show brain anatomy
