In need of constraint: Understanding the role of the cingulate cortex in the impulsive mind.

摘要: Impulsive behavior often occurs without forethought and can be driven by strong emotions or sudden impulses, leading to problems in cognition across a wide range of situations. Although neuroimaging studies have explored the neurocognitive indicators impulsivity, large-scale functional networks that contribute different aspects impulsive remain unclear. In particular, we lack coherent account why impulsivity is associated with such broad psychological features. Here, use resting state connectivity, acquired two independent samples, investigate neural substrates underlying self-reported impulsivity. Based on involvement anterior cingulate cortex (ACC) cognitive but also affective processes, five seed regions were placed along caudal rostral gradient ACC. We found positive urgency was related connectivity between subgenual ACC bilateral parietal as retrosplenial potentially highlighting this connection being important modulation non-prospective, hastiness - Further, dimensions significant alterations supragenual ACC: (i) perseverance positively correlated dorsolateral prefrontal right inferior frontal gyrus (ii) premeditation inversely clusters within occipital cortex. Further analysis revealed these patterns overlapped multiple demand network, system implicated general control thought action. Together results demonstrate forms correlates, which are linked region This suggests poor perseveration might dysfunctions how zone interacts network allows proceed controlled way.
