Long-Term Potentiation (LTP)

Long-Term Potentiation is the ability of brain cells to retain how frequently they send signals to other brain cells. Brain cells that are used for mental exercises (such as languages and math problems) have a tendency to last longer than those that aren't used. This can vary both from person to person and within a single person's activities. If you practice your foreign language but don't practice algebra, you are more likely to forget the algebra and remember the language.
