Área de Brodmann 25 (BA25) is an area in the cerebral cortex of the brain and delineated based on its cytoarchitectonic characteristics. It is also called the subgenual area, area subgenualis or subgenual cingulate. It is the 25th "Área de Brodmann" defined by Korbinian Brodmann (thus its name). BA25 is located in the cingulate region as a narrow band in the caudal portion of the subcallosal area adjacent to the paraterminal gyrus. The posterior parolfactory sulcus separates the paraterminal gyrus from BA25. Rostrally it is bound by the prefrontal area 11 of Brodmann.[1] Contenido 1 Historia 2 Función 3 Patología 4 Imagen 5 notas y referencias 6 See also History Brodmann described this area as it is labeled now in 1909. Originally in 1905, Brodmann labeled the area as part of area 24. En 1909, he divided the area into area 24 y 25.[2] Function This region is extremely rich in serotonin transporters and is considered as a governor for a vast network involving areas like hypothalamus and brain stem, which influences changes in appetite and sleep; the amygdala and insula, which affect the mood and anxiety; the hippocampus, which plays an important role in memory formation; and some parts of the frontal cortex responsible for self-esteem.[3] Pathology One study has noted that BA25 is metabolically overactive in treatment-resistant depression and has found that chronic deep brain stimulation in the white matter adjacent to the area is a successful treatment for some patients.[4] A different study found that metabolic hyperactivity in this area is associated with poor therapeutic response of persons with Major Depressive Disorder to cognitive-behavioral therapy and venlafaxine.[5] Image Brodmann area 25 animation small.gif Animation.
