Cognitive and emotional influences in anterior cingulate cortex

Area of Science:

• Neuroscience
• Cognitive Neuroscience
• Affective Neuroscience

Background:

• The anterior cingulate cortex (ACC), part of the limbic system, was traditionally linked to affect.
• Neuroimaging since the late 1980s revealed ACC involvement in cognitive tasks.
• EEG studies identified error negativity in ACC, suggesting an error detection role.

Purpose of the Study:

• To review findings on ACC's role in attention, regulating cognitive and emotional processing.
• To explore the relationship between ACC subdivisions, cognition, and emotion.
• To discuss the developmental roles and potential correlation between ACC size and response regulation.

Main Methods:

• Review of lesion studies in humans and animals.
• Analysis of neuroimaging studies (EEG, fMRI).
• Integration of findings on error negativity, affect, and motivation.

Main Results:

• Evidence suggests ACC is integral to a circuit for attention, modulating both cognitive and emotional functions.
• Distinct ACC regions are implicated in specific cognitive and emotional processes.
• Error negativity is influenced by affective and motivational states, linking ACC to emotional regulation.

Conclusions:

• The ACC plays a crucial role in attention, integrating cognitive and emotional information for response regulation.
• Developmental changes and structural variations (e.g., cingulate size) may influence ACC's regulatory efficacy.
• Interactions between ACC subdivisions and other cortical areas are key to mental and emotional activity regulation.
