Where memory is concerned, the hippocampus is involved in processing semantic and episodic memories, but it does not do that for procedural memories.
hippocampus is located within the medial temporal lobe and and assumes critical parts in the combination of data from short-term memory to long term memory, and in spatial memory that empowers navigation. The hippocampus is situated under the cerebral cortex (allocortical) and in primates in the medial temporal lobe.
