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 term is ambiguous, with some authors [who?] including the paraterminal gyrus, the subcallosal area, the cingulate gyrus, the parahippocampal gyrus, the dentate gyrus, the hippocampus and the subiculum; [1] while the Terminologia Anatomica includes the cingulate sulcus, the cingulate gyrus, the isthmus of cingulate gyrus, the fasciolar gyrus ...
The cingulate cortex is a part of the "grand lobe limbique" of Broca (1878) that consisted of a superior cingulate part (supracallosal) and an inferior hippocampic part (infracallosal). [26] The limbic lobe was separated from the remainder of the cortex by Broca for two reasons: first because it is not convoluted, and second because the gyri ...
Management of the dawn phenomenon varies by patient and thus should be done with regular assistance from a patient's physician. Some treatment options include, but are not limited to, dietary modifications, increased exercise before breakfast and during the evening, and oral anti-hyperglycemic medications if a patient's HbA1c is > 7%.
Type 3 diabetes is a proposed pathological linkage between Alzheimer's disease and certain features of type 1 and type 2 diabetes. [1] Specifically, the term refers to a set of common biochemical and metabolic features seen in the brain in Alzheimer's disease, and in other tissues in diabetes; [1] [2] it may thus be considered a "brain-specific type of diabetes."
It forms the white matter core of the cingulate gyrus, following it from the subcallosal gyrus of the frontal lobe beneath the rostrum of corpus callosum to the parahippocampal gyrus and uncus of the temporal lobe. [2] Neurons of the cingulum receive afferent fibers from the parts of the thalamus that are associated with the spinothalamic tract ...
