Coffee, Coffee & Coffee
Is it possible for the consumption of coffee to have memory-enhancing effects? A recent article in Nature Neuroscience reveals that caffeine found in coffee, tea and other beverages may boost your memory.
The study had half the participants who were not regular caffeine consumers take 200 milligrams of caffeine and other half take a placebo (sugar pill) exactly 5 minutes after studying a series of images presented to them. The study collected saliva samples of the participants before the treatment, one, three and 24 hours afterwards to track the levels of caffeine in the participant. The subjects would then be tested the next day on the series of images presented the day before.
A cup of brewed coffee can range anywhere between 95-200 milligrams of caffeine and green tea can contain 24-40mg.
Participants who received the caffeine were better able to identify the images the day before as “same, but different” which seems to be the process (pattern separation) that is enhanced by caffeine.
