Chronic pain as a state-constrained brain network disorder: a dynamical systems model integrating physiological regulation and self-organisation

1

Chronic pain is recognized as a disorder of brain network organization, involving alterations in the salience network, default mode network, and central executive network.
2

Neuroimaging studies show that persistent pain is linked to increased salience network activity and altered connectivity in the default mode network.
3

The proposed state-constrained triple-network model incorporates physiological regulation, suggesting it shapes chronic pain network dynamics.
4

Chronic pain may arise from interactions between physiological regulation and brain network dynamics, influencing pain-related network states over time.
5

The model emphasizes the importance of physiological context in understanding the stability and variability of chronic pain experiences.
