Although the memories in your short-term memory will be forgotten after about 20 to 45 seconds, rehearsal of the information converts them into the long-term memory.

The way the information will be encoded depends on what kind of information it is and through what senses your brain received it. Even if the information would reach the long-term memory, the information that is stored can be forgotten through interference or retrieval failure. Sometimes losing a memory happens because it never actually made it into the long-term memory at all. The olfactory memory refers to the recollection of odours. Brain Works Loretta G. Breuning, PhD a 200-million-year success story. Our memory is our ability to encode, store and recall information from our brain. Depending on the information, a different memory type will store the information. This duration can vary from a few minutes to an entire lifetime. When we store a memory, we are receiving, encoding and storing information. *The key difference between short-term memory (STM) and working memory (WM) is that STM is mainly maintenance of information while WM is maintenance and manipulation of information.
