Frontoparietal Network
A large-scale brain network that coordinates activity between frontal and parietal regions, playing a crucial role in cognitive control, conscious awareness, and attention.
Frontoparietal Network
The frontoparietal network (FPN) represents a fundamental large-scale brain system that connects regions in the frontal lobe and parietal lobe, serving as a critical infrastructure for conscious cognition and executive function.
Anatomical Structure
Core Components
- dorsolateral prefrontal cortex (dlPFC)
- posterior parietal cortex
- anterior prefrontal cortex
- inferior parietal lobule
Connectivity Patterns
The network features robust bilateral connections through:
- Long-range white matter tracts
- Dynamic functional coupling
- neural synchronization patterns
