What is the posterior cingulate?

What is the posterior cingulate?

The posterior cingulate cortex (PCC) is the caudal part of the cingulate cortex, located posterior to the anterior cingulate cortex. This is the upper part of the “limbic lobe”. The cingulate cortex is made up of an area around the midline of the brain.

What is the posterior cingulate cortex function?

The function of the posterior cingulate cortex (PCC) is uncertain. It is a central node of the default mode network (DMN), a set of brain regions showing strongly correlated neural activity and a reliable deactivation in activity during many cognitive tasks (Raichle et al., 2001).

What is the default mode network in the brain?

Thus, the default mode network is a group of brain regions that seem to show lower levels of activity when we are engaged in a particular task like paying attention, but higher levels of activity when we are awake and not involved in any specific mental exercise.

What is the dorsal anterior cingulate cortex?

Dorsal anterior cingulate cortex (dACC) is a brain region that subserves cognition and motor control, but the mechanisms of these functions remain unknown. These findings should be of interest to those studying reward, cognition, emotion, motivation, and motor control.

What is posteromedial cortex?

The posteromedial cortex (PMC) is a collective term for an anatomically heterogeneous area of the brain constituting a core node of the human default mode network (DMN), which is engaged during internally focused subjective cognition such as autobiographical memory.

What happens if the cingulate cortex is damaged?

If the anterior cingulate cortex becomes damaged, however, the patient will struggle to associate certain actions with emotions such as fear or sadness. This can lead to anti-social behavior because the person does not realize that their actions can hurt others or cause them distress.

Is the amygdala part of the DMN?

These regions include the hippocampus, amygdala, anterior cingulate, ventromedial prefrontal cortex, and dorsal medial prefrontal cortex and fall within the anterior portion of the DMN. Our goal was to examine the role of the DMN in emotional modulation in depression.

What part of the brain is responsible for rumination?

Rumination is specifically correlated with the DMN core regions and the dorsal medial prefrontal cortex subsystem.

What is the function of the anterior cingulate cortex?

front-most portion of the cingulate cortex, the anterior cingulate cortex (or ACC) has been implicated in several complex cognitive functions, such as empathy, impulse control, emotion, and decision-making. Anterior cingulate cortex (ACC) in purple.
