A type of magnetic resonance imaging ( MRI) that’s particularly useful for getting clear pictures of the body’s internal structure was used to observe the participants’ brains. The researchers recorded cortical thickness for 34 regions, averaging the measurement across the brain’s left and right hemispheres. They also looked at 45 people who had never had AUD, measuring their cortical thickness at baseline and again about 9 months later to confirm the areas that were measured stayed the same.
