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
Long-term memory Research by Manelis, Hanson, and Hanson (2011) found that the reactivation of the parietal and occipital regions was associated with implicit memory. Procedural memory is considered non-declarative memory or unconscious memory which includes priming and non-associative learning. The first part of nondeclarative memory (implicit memory) involves priming. Priming occurs when you do something faster after you have already done that activity, such as writing or using a fork. Other categories of memory may also be relevant to the discussion of long-term memory. For example: Emotional memory, the memory for events that evoke a particularly strong emotion, is a domain that
