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 .
Adaptive or closed-loop deep brain stimulation is a technique in which a steering signal influences when, with which amplitude or at which electrode contacts the DBS system is activated. This steering signal can be a physiological sensing signal, which is typically either recorded from the same implanted electrode or a cortical electrode/ ECoG ...
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). [31] 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 ...
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 anterior cingulate cortex can be divided anatomically based on cognitive , and emotional components. [5] The dorsal part of the ACC is connected with the prefrontal cortex and parietal cortex , as well as the motor system and the frontal eye fields , [ 6 ] making it a central station for processing top-down and bottom-up stimuli and ...
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.
Electroconvulsive Therapy (ECT): ECT remains a cornerstone of interventional psychiatry, especially for severe, treatment-resistant depression and catatonia. The procedure involves controlled electrical currents to the brain, inducing a seizure that can lead to significant improvements in mood and behavior.
Broca named the limbic lobe in 1878, identifying it with the cingulate and parahippocampal gyri, and associating it with the sense of smell - Treviranus having earlier noted that, between species, the size of the parahippocampal gyrus varies with the size of the olfactory nerve. [2]
