===Division of long-term memory===
In the case of long-term memory it is unlikely that different types of information, such as the motor skills to ride a bike, memory for vocabulary, and memory for personal life events are stored in the same fashion. [[Endel Tulving]] notes the importance of encoding specificity in long-term memory.  To clarify, there are definite differences in the way information is stored depending on whether it is episodic (memories of events), procedural (knowledge of how to do things), or semantic (general knowledge).<ref name=TulvingThompson1973 /> A short (non-inclusive) example comes from the study of [[Henry Molaison]] (H.M.): learning a simple motor task (tracing a star pattern in a mirror), which involves implicit and procedural long-term storage, is unaffected by bilateral lesioning of the hippocampal regions while other forms of long-term memory, like vocabulary learning (semantic) and memories for events, are severely impaired.<ref name=Milner1962 />
