Frontoparietal Network

Diagram of the frontoparietal network

The frontoparietal network is a large-scale brain network that plays a crucial role in cognitive control, attention, and working memory. It is primarily composed of regions in the frontal lobe and the parietal lobe of the cerebral cortex. This network is essential for the integration of sensory information and the execution of complex cognitive tasks.

Structure

The frontoparietal network includes several key brain regions:

• The dorsolateral prefrontal cortex (DLPFC), which is involved in executive functions such as planning and decision-making.
• The anterior cingulate cortex (ACC), which plays a role in error detection and conflict monitoring.
• The intraparietal sulcus (IPS), which is important for spatial attention and the manipulation of information in working memory.

These regions are interconnected through a series of white matter tracts, allowing for efficient communication and coordination of cognitive processes.

Function

The frontoparietal network is activated during tasks that require:

• Cognitive control: The ability to regulate thoughts and actions in accordance with internal goals.
• Attention: The capacity to focus on relevant stimuli while ignoring distractions.
• Working memory: The temporary storage and manipulation of information needed for complex cognitive tasks.

This network is also involved in decision making, problem-solving, and the regulation of emotions.

Clinical Significance

Dysfunction in the frontoparietal network has been associated with several neurological and psychiatric conditions, including:

• Attention deficit hyperactivity disorder (ADHD)
• Schizophrenia
• Depression
• Alzheimer's disease

Understanding the frontoparietal network's role in these conditions can help in developing targeted therapies and interventions.
