Anterior Cingulate Cortex and the Control of Dynamic Behavior in Primates

Area of Science:

• Neuroscience
• Cognitive Science
• Computational Psychiatry

Background:

• Continuous behavior in dynamic environments requires sophisticated brain mechanisms for action selection and learning.
• Environmental uncertainty and volatility necessitate flexible responses across multiple timescales.

Purpose of the Study:

• To review the role of the anterior cingulate cortex (ACC) in mediating continuous behavior control.
• To highlight the ACC's suitability for integrating information and adapting to dynamic contexts.

Main Methods:

• Review of electrophysiological and circuit disruption studies in primates.
• Discussion of implications for human neuropsychiatric disorders.
• Comparison of primate research with rodent medial frontal cortical studies.

Main Results:

• The ACC is interconnected with key regions involved in valuation and action selection.
• The ACC integrates diverse information across timescales, encoding value, uncertainty, and future outcomes.
• The ACC flexibly signals behaviorally relevant information in a context- and action-specific manner.
• The ACC dynamically controls information-seeking behaviors to resolve uncertainty.

Conclusions:

• The anterior cingulate cortex (ACC) is a critical hub for adaptive behavior control in dynamic environments.
• ACC function is relevant for understanding and potentially treating neuropsychiatric disorders.
• Further research in rodents can complement primate studies on ACC function.
