HIPPOCAMPUS

The hippocampus is a major component of the brains of humans and other vertebrates. It belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus is a part of the cerebral cortex; and in primates it is located in the medial temporal lobe, underneath the cortical surface. 

The earliest description of the HIPPOCAMPUS- IE: the ridge running along the floor of the temporal horn of the lateral ventricle comes from the Venetian anatomist Julius Caesar Aranzi (1587), who likened it first to a  seahorse (Latin: hippocampus from Greek: ἵππος, "horse" and κάμπος, "coiled").
