Hunger hormone helps memory

  • A little more lit searching would have been appropriate :-). For instance: "Whether ghrelin affects memory in general or only memories pertaining to food remains unknown is incorrect: see for example http://www.nature.com/neuro/journal/v9/n3/abs/nn1656.html which is the 3rd hit for 'ghrelin memory' in Google, after refs to this article... [Yes, ghrelin acts to improve hippocampal memory, increase spine density, and modulate plasticity]

  • Hi Ewan, Thanks for commenting! I believe the paper you're referring to is based on work performed in rodents. We alluded to that work in the article, but included the caveat that it isn't clear how that will translate to human memory.
