Memory and sleep. There is a certain relationship between them. It is believed that the memory can be improved when one sleeps. For example, students A and B learn a similar topic - matter - in a science lesson. Student A learns and sleeps after the lesson while student B continues to study the topic, despite having a tired mind.
Under this scenario, student A will get a better chance of remembering the content. This is due to the fact when one is asleep, the mind actually has an uninterrupted communication between the neocortex and the hipocampus (the brain's memory systems). Memories are first formed in the hipocampus. In order for memory to be retained, it has to be channeled to neocortex. The neocortex will form a more stable memory and simultaneously, it will form a link to related memories created earlier. Thus the new memory can be more likely remembered.
Sleeping is a way that memory can be better stored and yet the brain can help with organising the newly acquired information orderly. Maybe it is good option to sleep right away after you have finished your exam revision.
