There is no specific memory storage area in the brain, instead information is bundled in different association areas of the cerebral cortex. This means that different parts of the brain will be activated related to different aspects of learning. For example, memorizing math computations activates a different area of the brain than remembering the steps to the samba. What most people are concerned about is not so much how information is stored in memory, but how to use it more effectively and prevent deterioration.
