New research from Carnegie Mellon University is reshaping how scientists understand Parkinson’s disease. Instead of a single condition, the study shows that key symptoms — tremor and slowed movement — arise from disruptions in different brain circuits.

Led by neuroscientist Aryn Gittis, the research identifies distinct patterns of neural activity in the motor thalamus, a central hub for movement control. These findings help explain why current treatments, which primarily target dopamine, work well for some symptoms but not others.

By mapping the specific circuits behind different symptoms, this work opens the door to more precise, personalized therapies and could improve approaches like deep brain stimulation. It also provides a new model for studying tremor, a long-standing challenge in Parkinson’s research.

Carnegie Mellon University’s Aryn Gittis and colleagues suggest the most recognizable symptoms of Parkinson's disease result from disruptions in different motor circuits of the brain, an insight that could help explain why current treatments don’t work equally for all patients.

How can generative AI support student learning in the lab? Carnegie Mellon’s Annie Arnold is exploring that question through a GAITAR Fellowship focused on improving how students interpret and present scientific data.

In her Advanced Organic Chemistry Laboratory course, Arnold is studying whether structured dialogue with AI can help students think more critically about how they visualize data — not just what they show, but why and for whom. The goal is to strengthen reasoning and communication skills, not replace them.

Supported by CMU’s Eberly Center, the project is part of a broader effort to build evidence-based approaches for using AI in education. If successful, the approach could be adapted across disciplines, helping students develop stronger analytical and decision-making skills in data-driven fields.

Annie Arnold, special faculty in chemistry at Carnegie Mellon University, has received a fellowship through CMU’s Generative Artificial Intelligence Teaching as Research (GAITAR) Initiative to study how — and whether — generative AI can meaningfully support student learning in laboratory cours...
