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 ...

The neurotransmitter dopamine influences the activity of a wide variety of brain areas. A deficiency of this substance can have drastic consequences: The death of dopamine-producing nerve cells in the ...

Over the past dozen years, great strides have been made in identifying mutations that cause Alzheimer (AD) and Parkinson (PD) diseases. But while familial AD cases result from mutations that impinge ...

In a recent study published in Progress in Neurobiology, researchers discover that the substantia nigra of individuals with Parkinson’s disease had a higher concentration of pheomelanin, as well as ...

A research team led by McGill University has taken a close look at a long-standing idea about Parkinson’s disease and found ...
