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 in neurons. Unlike short-term memory and working memory, intermediate-term memory requires changes in translation to occur in order to function. While ITM requires only changes in translation, induction of long-term memory requires changes in transcription as well. The change from short-term memory to long-term memory is thought to dependent on CREB, which regulates transcription, but because ITM does not involve a change in transcription, it is thought to be independent of CREB activity. According to the definition of ITM proposed by Sutton "et al." in 2001, it disappears completely before long-term memory is induced. Intermediate-term memory Intermediate-term memory (ITM) is
