The common hippopotamus (Hippopotamus amphibius), or hippo, is a large, mostly herbivorous mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). The name comes from the ancient Greek for river horse (á¼±ÏÏÎ¿ÏÏÏÎ±Î¼Î¿Ï).
The hippocampus (named after its resemblance to the seahorse, from the Greek á¼±ÏÏÏÎºÎ±Î¼ÏÎ¿Ï, seahorse from á¼µÏÏÎ¿Ï hippos, horse and ÎºÎ¬Î¼ÏÎ¿Ï 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.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.The hippocampus is located under the cerebral cortex; and in primates it is located in the medial temporal lobe, underneath the cortical surface.amage to the hippocampus can also result from oxygen starvation (hypoxia), encephalitis, or medial temporal lobe epilepsy. People with extensive, bilateral hippocampal damage may experience anterograde amnesia âthe inability to form and retain new memories.
