Subgenual cingulate activity reflects individual differences in empathic concern.
Recent fMRI studies linked subgenual cingulate cortex (SCC) activity with feelings of guilt for acting counter to social values and altruistic donations towards societal causes. We hypothesized that SCC activity across those different tasks was driven by feelings of attachment. In order to investigate this further, we used fMRI to probe the association of empathic concern and strength of SCC ac...
متن کاملAdolescent subgenual anterior cingulate activity is related to harm avoidance.
Recent adult studies suggest that the subgenual anterior cingulate cortex (sgACC) is involved in fundamental mental operations such as affective processing and inhibitory control. However, little is known about inhibition-associated sgACC function in adolescents, and there are no published data regarding whether personality characteristics are related to inhibition-associated sgACC brain activi...
متن کاملDepressed adolescents demonstrate greater subgenual anterior cingulate activity.
Neuroimaging studies implicate the subgenual anterior cingulate cortex (sgACC) as a critical brain region in adult depression. However, unlike adult depression, little is known about the underlying neural substrates of adolescent depression, and there are no published data examining differences in sgACC activation between depressed and healthy adolescents. This study used functional magnetic re...
متن کاملEndogenous and exogenous glucocorticoids decrease plasma ghrelin in humans.
OBJECTIVE The orexigenic and adipogenic peptide hormone ghrelin is predominantly produced and secreted by the stomach and seems to transduce changes in food intake to specific neuronal circuits in the brain. The activity of ghrelin also includes stimulatory effects on the corticotropic system. However, little is known about the influence of glucocorticoids on ghrelin levels. We therefore studie...
متن کاملModulation of subgenual anterior cingulate cortex activity with real-time neurofeedback.
The advent of real-time neurofeedback techniques has allowed us to begin to map the controllability of sensory and cognitive and, more recently, affective centers in the brain. The subgenual anterior cingulate cortex (sACC) is thought to be involved in generation of affective states and has been implicated in psychopathology. In this study, we examined whether individuals could use real-time fM...
