The paper examines how cortical morphology correlates with long-term placebo responses in multiple sclerosis patients, finding that non-responders have a more small-world-like cortical topology and lesion load inversely predicts cortical thickness in specific brain regions.

The paper models how brain tissue orientation, diffusion, and perivascular spaces affect dynamic susceptibility contrast MRI signals and finds that orientation significantly influences the contrast agent's R2* increase.
