This paper models the brain as a multiplex network to show that healthy aging involves a progressive divergence between structural and functional connectomes, with subcortical hubs showing significant age-related decoupling.

The paper compares effective connectivity in chronic pain patients and placebo responders using resting-state fMRI to identify markers of nociception and placebo response.

The paper shows that increased segregation and reduced integration in brain networks enhance perceptual binding of cross-modal stimuli using fMRI and computational analysis.

This study identifies enhanced top-down effective connectivity in sensorimotor cortices as a marker of trait somatic anxiety using resting-state fMRI and DCM.

The paper investigates altered effective connectivity in sensorimotor cortices using resting-state fMRI and DCM, finding changes associated with depression severity and treatment response.

This study investigates the functional organization of visual streams using fMRI, finding input-based dissociation and context-dependent plasticity rather than fixed ventral/dorsal segregation.
