Cornell study finds pupil size during sleep reflects how the brain processes new and old memories.
Cornell University researchers found that pupil size during sleep indicates how the brain processes memories.
In non-REM sleep, smaller pupils are linked to the consolidation of new memories, while larger pupils are associated with the integration of older memories.
This discovery, made by studying mice, could lead to better memory enhancement techniques for humans and improve artificial neural networks.
