The hippocampus contains high levels of glucocorticoid receptors, which make it more vulnerable to long-term stress than most other brain areas. [122] There is evidence that humans having experienced severe, long-lasting traumatic stress show atrophy of the hippocampus more than of other parts of the brain. [ 123 ]
Pytheas* speaks of an estuary of the Ocean named Metuonis and extending for 750 miles, the shores of which are inhabited by a German tribe, the Guiones. From here it is a day's sail to the Isle of Abalus, to which, he states, amber is carried in spring by currents, being an excretion consisting of solidified brine.
The CA areas are all filled with densely packed pyramidal cells similar to those found in the neocortex. After CA1 comes an area called the subiculum. After this comes a pair of ill-defined areas called the presubiculum and parasubiculum, then a transition to the cortex proper (mostly the entorhinal area of the cortex).

Winged hippocamp in an Art Deco fountain, Kansas City, Missouri, (1937). The hippocampus, or hippocamp or hippokampos (plural: hippocampi or hippocamps; Ancient Greek: ἱππόκαμπος, from ἵππος, 'horse', and κάμπος, 'sea monster' [1]), sometimes called a "sea-horse" [2] in English, [citation needed] is a mythological creature mentioned in Etruscan, Greek, Phoenician, [3 ...
The hippocampal formation is a compound structure in the medial temporal lobe of the brain. It forms a c-shaped bulge on the floor of the inferior horn of the lateral ventricle . [ 1 ] Typically, the hippocampal formation is said to included the dentate gyrus , the hippocampus , and the subiculum . [ 2 ]
The parietal lobe is located directly behind the central sulcus, superior to the occipital lobe and posterior to the frontal lobe, visually at the top of the back of the head. [18] The make up of the parietal lobe is defined by four anatomical boundaries in the brain, providing a division of all the four lobes. [18]
The name derives from its position at the back of the head, from the Latin ob, 'behind', and caput, 'head'. The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. [1] The primary visual cortex is Brodmann area 17, commonly called V1 (visual
