CA2 is probably the most enigmatic of the hippocampal fields. It is small in size (in humans
about 500 μm across the mediolateral axis), and yet, it is involved in important functions …

In the brain, the hippocampus is enriched with mineralocorticoid receptors (MR; Nr3c2), a
ligand-dependent transcription factor stimulated by the stress hormone corticosterone in …

The hippocampus is a center of learning, memory, and spatial navigation. This region is
divided into the CA1, CA2, and CA3 areas, which are anatomically different from each other …

Described by Lorente de Nó as a small area between CA1 and CA3, area CA2 then
disappeared from most representations of the hippocampal diagram. While it is …

Many calcium-binding proteins are expressed in a region-and cell-type specific manner in
the mammalian hippocampus. Neuronal calcium-binding proteins (NECABs) are also …

Abstract Since 1959, the Russian Farm‐Fox study has bred foxes to be either tame or, more
recently, aggressive, and scientists have used them to gain insight into the brain structures …

Background Post-traumatic stress disorder (PTSD) causes intrusive symptoms and
avoidance behaviours due to dysregulation in various brain regions, including the …

Both drawings are of tissue from mice. gl As yet, no molecular marker has been identified
that clearly distinguishes between the CA2 neurons receiving mossy fibers, and those in …

Prairie voles (Microtus ochrogaster) and Syrian, or golden, hamsters (Mesocricetus auratus)
are closely related to mice (Mus musculus) and are commonly used in studies of social …

Although it is well-known that the hippocampus mediates declarative memory (the repository
of information of people, places, things and events) and influences behavior, the differential …
