Is anterior cingulate cortex necessary for cognitive control?
Functional neuroimaging studies in normal humans suggest that dorsal anterior cingulate cortex (dACC) plays an important role in cognitive control. This brain area is reliably activated when tasks require the ongoing adjustment of the allocation of attention. The dACC has come to occupy a central role in theories of attention and cognitive control, which hold that dACC either monitors response ...
متن کاملSpine growth in the anterior cingulate cortex is necessary for the consolidation of contextual fear memory.
Remodeling of cortical connectivity is thought to allow initially hippocampus-dependent memories to be expressed independently of the hippocampus at remote time points. Consistent with this, consolidation of a contextual fear memory is associated with dendritic spine growth in neurons of the anterior cingulate cortex (aCC). To directly test whether such cortical structural remodeling is necessa...
متن کاملApplication of magnetic resonance spectroscopy for evaluating metabolic alteration in anterior cingulate cortex in Alzheimer's disease
Introduction: Alzheimer’s disease (AD) is the most common cause of dementia worldwide. Mild cognitive impairment (MCI) is often the prodromal stage to AD. Most patients with MCI harbor the pathologic changes of AD and demonstrate transition to AD at a rate of 10–15% per year. Accumulating evidence indicates that the asymmetry changes of left and right brain have happened in the early stage of A...
متن کاملCognitive Control Signals in Posterior Cingulate Cortex
Efficiently shifting between tasks is a central function of cognitive control. The role of the default network - a constellation of areas with high baseline activity that declines during task performance - in cognitive control remains poorly understood. We hypothesized that task switching demands cognitive control to shift the balance of processing toward the external world, and therefore predi...
متن کاملPreparatory activity and connectivity in dorsal anterior cingulate cortex for cognitive control
Dorsal anterior cingulate cortex (dACC) is composed of functionally distinct subregions that may contribute to the top-down control of response selection and preparation. Multiple motor areas have been identified in dACC, including an anterior zone implicated in conflict monitoring and a caudal zone involved in movement execution. This study tested the involvement of a third cingulate area, the...
