This study uses cTBS to inhibit the vmPFC and shows reduced Go responses, slower reaction times, and increased reward prediction error signals in subcortical regions.

This study investigates chronic pain in fibromyalgia using neuroimaging markers but finds no significant differences in brain function or structure associated with chronic, stimulus-independent pain.

The paper evaluates the ComBat method for multi-site diffusion MRI harmonization, finding that it preserves biological variability in some sites but not others and is sensitive to preprocessing differences.
