Hippocampus Thomas Henry Huxley and Richard Owen, satirised as the Great Hippocampus Question. The term hippocampus minor fell from use in anatomy textbooks, and was officially removed in the Nomina Anatomica of 1895. Today, the structure is just called the hippocampus, with the term "Cornu Ammonis" surviving in the names of the hippocampal subfields CA1-CA4. The term "limbic system" was introduced in 1952 by Paul MacLean to describe the set of structures that line the edge of the cortex (Latin "limbus" meaning "border"): These include the hippocampus, cingulate cortex, olfactory cortex, and amygdala. Paul MacLean later suggested that the limbic structures
Eating disorders and memory mechanism has been found in the food-reward system in eating disorder studies. Neurons located in different structures of the medial temporal lobe are what cause the transformation from an egocentric to an allocentric representation in space. The hippocampus generates allocentric representations for long-term memory, and the parietal cortex, retrosplenial cortex, entorhinal cortex, and hippocampus are part of a network that processes allocentric spatial information. The lateral entorhinal cortex carries nonspatial information from the perirhinal cortex to the dorsal hippocampus where it is then combined with the medial entorhinal cortex to create object-place or event-place representations in the hippocampus.
