Networks for Movement

Mapping signals from the brain's basal ganglia – region involved in movement and learning and more

Networks for Movement

Nestled deep within the brain is the basal ganglia, a cluster of neurons that controls various behaviours including how we move our limbs. Damage to these neurons and their networks can lead to conditions that affect our ability to make controlled movements, such as Parkinson’s disease. To better understand how information travels from the basal ganglia to the various brain regions involved in movement and behaviour, scientists created a precise map in mice of the networks originating from an area of the basal ganglia called the substantia nigra. They tracked electrical signals leaving from substantia nigra neurons as they travelled along pathways called axons (in green) to the rest of the brain by forming connections (in red) with other neurons. The detailed networks this map revealed could be used by other researchers to understand what type of information is carried along each connection and, ultimately, how animals move.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
