Caffeine and related xanthine compounds are psychostimulants that affect memory and learning. Caffeine is consumed by a large population of the world, so it is necessary to know its effects on brain. This study aims to determine the effects of caffeine on memory acquisition, memory consolidation, memory retention and learning. We gathered data where rats were used for this study and experiments on inhibitory avoidance task and habituation. Different doses of caffeine were used, 30 minutes before and after training and 30 minutes before test session. The research showed that caffeine improves memory consolidation but at low to moderate dozes. Caffeine affects memory in different ways on different dozes and it also depends on the kind of memory task.
