Within the human brain, movement is coordinated by a brain region called the striatum, which sends instructions to motor neurons in the brain. Those instructions are conveyed by two pathways, one that ...

A finding by a McGill-led team of neuroscientists could open doors to new treatments for a range of psychiatric and neurological disorders attributed to dysfunctions in specific dopamine pathways. For ...

For the first time, dopamine regulation has been mapped in real time, deep inside the brains of three humans, revealing how the brain neurotransmitter plays an essential role in not just recognizing ...

The caudate nucleus (green) is a subcortical brain region located in the striatum. The striatum is one of several neural structures that make up the basal ganglia (colored regions) located below the ...

For decades, Parkinson’s disease has been framed as a simple story of dwindling dopamine, a slow erosion of the brain’s movement signal. A wave of new research is now overturning that picture, ...
