Pupils may reveal memories you are reliving during sleep, scientists say

A new study has investigated the link between pupil dilation/contraction and memory processing during sleep. The study titled, "Sleep microstructure organizes memory replay", published in the journal Nature and conducted by scientists at Cornell University, Ithaca, claims that pupil size while sleeping could indicate the memories you are reliving in your dreams. Using advanced eye-tracking technology combined with EEG (electroencephalogram), the…

The Surprising Role of Pupils in Memory Formation

New York: The pupil of the eye is key to understanding how, and when, the brain forms strong, long-lasting memories, according to a mice study.  Researchers from Cornell University in the US found that new memories are being replayed and consolidated when the pupil is contracted during a substage of non-REM sleep. And when the pupil is dilated, the process repeats for older memories. The team explained that the brain prevents “catastrophic forge…

Pupil size during sleep reveals how memories are sorted, preserved: Study

The dilation or contraction of the pupil of the eye during sleep can reveal whether the brain is recalling new or older memories, scientists have found. Their study, published in the journal Nature, found that the size of the pupil can reveal how and when the brain forms strong, long-lasting memories. Researchers at Cornell University in the US attached electrodes to the brains of mice and monitored the rodents with eye-tracking cameras. They fo…

Η διάταση ή η συστολή της κόρης του ματιού κατά τη διάρκεια του ύπνου μπορεί να αποκαλύψει αν ο εγκέφαλος ανακαλεί νέες ή παλαιότερες αναμνήσεις, διαπίστωσαν επιστήμονες. Η μελέτη τους, που δημοσιεύθηκε στο περιοδικό «Nature», διαπίστωσε πως το μέγεθος της κόρης μπορεί να αποκαλύψει πώς και πότε ο εγκέφαλος σχηματίζει δυνατές, μακροχρόνιες αναμνήσεις. Ερευνητές στο Πανεπιστήμιο Κορνέλ στις ΗΠΑ προσάρτησαν ηλεκτρόδια σε εγκεφάλους ποντικών και πα…
