Brodmann area 25 (BA25) is the subgenual area, area subgenualis or subgenual cingulate area in the cerebral cortex of the brain and delineated based on its cytoarchitectonic characteristics. It is the 25th " Brodmann area " defined by Korbinian Brodmann (thus its name).
The subcallosal area (parolfactory area of Broca) is a small triangular field on the medial surface of the hemisphere in front of the subcallosal gyrus, from which it is separated by the posterior parolfactory sulcus; it is continuous below with the olfactory trigone, and above and in front with the cingulate gyrus; it is limited anteriorly by the anterior parolfactory sulcus.
The subcallosal gyrus (paraterminal gyrus, peduncle of the corpus callosum) is a narrow lamina on the medial surface of the hemisphere in front of the lamina terminalis, behind the parolfactory area, and below the rostrum of the corpus callosum. It is continuous around the genu of the corpus callosum with the indusium griseum.
The adjacent subcallosal cingulate gyrus has been implicated in major depression and research indicates that deep-brain stimulation of the region could act to alleviate depressive symptoms. [38] Although people with depression had smaller subgenual ACCs, [39] their ACCs were more active when adjusted for size.
In the guenon this area is referred to as area 24 of Brodmann-1905.It includes portions of the cingulate gyrus and the frontal lobe.The cortex is thin; it lacks the internal granular layer (IV) so that the densely distributed, plump pyramidal cells of sublayer 3b of the external pyramidal layer (III) merge with similar cells of the internal pyramidal layer (V); the multiform layer (VI) is very ...
Barn cats are cats that—well, live in a barn and help keep the mice out. As barns are warm, dry spaces with plenty of grain feed, they are naturally a desirable home for all kinds of rodent ...
In cingulate or subfalcine herniation, the most common type, the innermost part of the frontal lobe is scraped under part of the falx cerebri, the dura mater at the top of the head between the two hemispheres of the brain. [8] [13] Cingulate herniation can be caused when one hemisphere swells and pushes the cingulate gyrus by the falx cerebri. [7]
Most cat bites just need to be cleaned and treated with antibiotics and tetanus shots, but a 2019 study of serious cat bites showed that human patients needed an average of three days of ...
