The [[hippocampus]] participates in the encoding, consolidation, and retrieval of memories.<ref name=a /> The hippocampus is located in the medial temporal lobe (subcortical), and is an infolding of the medial temporal cortex.<ref name=a>Gazzaniga, Michael S., Richard B.

These stages do not need to occur successively, but are, as studies seem to indicate, and they are broadly divided in the neuronal mechanisms that they require or even in the hippocampal areas that they seem to activate. According to Gazzaniga, "encoding is the processing of incoming information that creates memory traces to be stored."<ref name=a /> There are two steps to the encoding process: "acquisition" and "consolidation". During the acquisition process, stimuli are committed to the short term memory stage.<ref name=a /> Then, consolidation is where the hippocampus along with other cortical structures stabilize an object within the long term memory stage, awhich process strengtheningstrengthens over time and time again, and is a process for from whomwhich a number of theories have arisen to explain to as of why and how itthe actuallyunderlying worksmechanism.<ref name=a /> After encoding, the hippocampus is capable of going through the retrieval process. The retrieval process consists of accessing stored information; this allows learned behaviors to experience conscious depiction and execution.<ref name=a /> Encoding and retrieval are both affected by [[neurodegenerative]] and [[anxiety disorders]] and [[epilepsy]].
