Reduced somatostatin in subgenual anterior cingulate cortex in major depression.
Converging evidence suggests a central role for dysfunction of the subgenual anterior cingulate cortex (sgACC) in the pathophysiology of major depressive disorder (MDD). Underlying mechanisms may include altered GABAergic function. Expression of somatostatin (SST), an inhibitory neuropeptide localized to a subset of GABA neurons, has been shown to be lower in the dorsolateral prefrontal cortex ...
متن کاملThe subgenual anterior cingulate cortex in mood disorders.
The anterior cingulate cortex (ACC) ventral to the genu of the corpus callosum has been implicated in the modulation of emotional behavior on the basis of neuroimaging studies in humans and lesion analyses in experimental animals. In a combined positron emission tomography/magnetic resonance imaging study of mood disorders, we demonstrated that the mean gray matter volume of this "subgenual" AC...
متن کاملBrain-derived neurotrophic factor signaling and subgenual anterior cingulate cortex dysfunction in major depressive disorder.
OBJECTIVE The subgenual anterior cingulate cortex is implicated in the pathology and treatment response of major depressive disorder. Low levels of brain-derived neurotrophic factor (BDNF) and reduced markers for GABA function, including in the amygdala, are reported in major depression, but their contribution to subgenual anterior cingulate cortex dysfunction is not known. METHOD Using polym...
متن کاملSubgenual anterior cingulate activation to valenced emotional stimuli in major depression.
Major depression has been associated with anomalous activation in the subgenual anterior cingulate cortex, but its response to emotional stimuli is poorly understood. The primary goal of this study was to compare levels of activation in the subgenual anterior cingulate cortex of diagnosed depressed and nondepressed participants in response to happy and sad facial expressions of affect. Whereas ...
متن کاملChanged Hub and Corresponding Functional Connectivity of Subgenual Anterior Cingulate Cortex in Major Depressive Disorder
Major depressive disorder (MDD) is one of the most prevalent mental disorders. In the brain, the hubs of the brain network play a key role in integrating and transferring information between different functional modules. However, whether the changed pattern in functional network hubs contributes to the onset of MDD remains unclear. Using resting-state functional magnetic resonance imaging (rs-f...
