Kathie Nunley reports:
“caffeine is not effective in improving task performance. (…) Apparently, caffeine increases Acetylcholine levels which block hippocampus consolidation, thus leading to poor memory formation and recall.”
Besides, “”If you get a full night sleep or 90 minute nap (more REM) this equals your best performance. Any mini-nap will give you better learning”
Nunley attributes these ideas to the following source: Sara Mednick, PhD, UC-San Diego.
“What can Sleep stages tell us about the mechanisms of memory consolidation?” presented at the APA national conference, San Diego, April 13, 2010.
