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
Intermediate-term memory phase of long-term memory, respectively—thus demonstrating the presence of a form of memory that exists between working memory and long-term memory, which they referred to as "intermediate-term memory". Though the idea of intermediate-term memory has existed since the 1990s, Sutton "et al." introduced a novel theory for the neural correlates underlying intermediate-term memory in "Aplysia" in 2001, where they described it as the primary behavioral manifestation of intermediate-term facilitation. In 2001, Sutton and colleagues proposed that intermediate-term memory possesses the following three characteristics: Because intermediate-term memory does not involve transcription, it likely involves the translation of mRNA transcripts already present
