How the brain plans and sequences everyday actions
Neural Population Geometry and Dynamics Underlying Multi-Step Cognitive-Motor Sequencing
This project looks at how connected brain areas plan and carry out multi-step movements so findings can help people with movement problems like Parkinson's disease.

What this research studies
You will read about research that records brain activity across multiple areas involved in planning and executing sequences of actions. The team trains rhesus macaques on a new task that requires using learned rules to produce multi-step movement plans on novel trials. While animals perform the task, researchers record large-scale neural signals from prefrontal cortex, supplementary motor area, premotor cortex, and the basal ganglia to see how upstream circuits set up whole action sequences. Results aim to reveal how the brain represents later steps 'just in time' and how breakdowns in this coordination may cause problems seen in Parkinson's and related disorders.
Who could benefit from this research
Good fit: People with Parkinson's disease or other conditions that cause trouble planning or sequencing movements would be the most relevant group to follow this research and potentially join future related human studies.
Not a fit: Patients whose problems stem from peripheral nerve or muscle disease rather than central brain sequencing may not directly benefit from findings focused on brain circuit dynamics.
Why it matters
Potential benefit: If successful, this work could clarify brain circuit failures that underlie planning and execution problems and guide new therapies or rehabilitation approaches for movement disorders.
How similar studies have performed: Prior human and animal work has shown motor and premotor areas are important for sequencing, but this large-scale, multi-area circuit recording approach is relatively novel.
