Upon analysing the data, it was found that two substages happened during the NREM (Non-Rapid Eye Movement) sleep. The pupils ...

Cornell researchers discovered that pupil dynamics during non-REM sleep separate new and old memory consolidation in mice.

Scientists have discovered a link between pupil size during non-REM sleep and the processing of new and old memories.

Summary: Researchers have discovered that pupil size during non-REM sleep correlates with memory consolidation. When pupils ...

While our body shuts down in slumber each day, the brain remains busy at work, filing through the day's recordings and making ...

A stage of sleep – reflected in the size of our pupils – is important to committing recent memories to the brain, which could ...

indicating a relationship between the pupil’s movement and cognitive state 2. Many studies since then have shown that the pupil can reflect changes in mental states, the intensity of cognition ...

Researchers from Cornell University, US, connected electrodes to the brains of a group of mice and tracked pupil movements during one of the stages of non-rapid eye movement sleep. The team found that ...

REM sleep may help the brain manage memory replay and consolidation. Cornell University researchers found that contracted pupils are linked to replaying recent memories, while dilated pupils are ...
