Olfaction the amygdala and is involved in emotional and autonomic responses to odor. It also projects to the hippocampus and is involved in motivation and memory. Odor information is stored in long-term memory and has strong connections to emotional memory. This is possibly due to the olfactory system's close anatomical ties to the limbic system and hippocampus, areas of the brain that have long been known to be involved in emotion and place memory, respectively. Since any one receptor is responsive to various odorants, and there is a great deal of convergence at the level of the olfactory bulb, it may
Hippocampal memory encoding and retrieval Hippocampal memory encoding and retrieval The hippocampus participates in the encoding and retrieval of memories. The hippocampus is located in the medial temporal lobe (subcortical), and is an infolding of the medial temporal cortex. The hippocampus plays an important role in the transfer of information from short-term memory to long-term memory during encoding and retrieval stages. These stages need not occur successively, but are, as studies indicate, broadly divided in the neuronal mechanisms they require or even in the hippocampal areas they activate. According to Gazzaniga, "encoding is the processing of incoming information that creates memory traces to be stored."
