Brain Imaging Technique: New Hope for Understanding Parkinson’s Disease

ANN ARBOR, Mich.— A non-invasive brain imaging technique gives new hope to patients with Parkinson’s disease in finding new and better treatment plans and tracking the disease progression, a new University of Michigan study shows.

The technique uses an MRI to measure resting state brain activity oscillations, said Rachael Seidler, associate professor in the School of Kinesiology and the Department of Psychology, and study author. (more…)

ANN ARBOR, Mich.—It’s unavoidable: breakdowns in brain connections slow down our physical response times as we age, a new study suggests.

This slower reactivity is associated with an age-related breakdown in the corpus callosum, a part of the brain that acts as a dam during one-sided motor activities to prevent unwanted connectivity, or cross-talk, between the two halves of the brain, said Rachael Seidler, associate professor in the University of Michigan School of Kinesiology and Department of Psychology, and lead study author.
