Hippocampus Hippocampus The hippocampus (named after its resemblance to the seahorse, from the Greek ἱππόκαμπος, "seahorse" from ἵππος "hippos", "horse" and κάμπος "kampos", "sea monster") is a major component of the brains of humans and other vertebrates. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. The hippocampus is located under the cerebral cortex (allocortical) and in primates in the medial temporal lobe. It contains two main
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
