A team of researchers is using a genetically modified version of the rabies virus to create the first comprehensive list of inputs that connect directly to dopamine neurons in two regions of the brain.Direct inputs to dopamine neurons: Green dots represent neurons providing inputs to dopamine neurons in the ventral tegmental area (VTA), while red dots represent neurons providing inputs to substantia nigra (SNc) dopamine neurons.

Parkinson’s disease is a neurological disorder that becomes progressively worse over time as the neurons in the substantia nigra area of the brain degenerate. This can greatly affect people's ability to move and induce symptoms commonly associated with Parkinson’s disease, such as rigidity, tremors and other uncontrollable...

MRI Technique Could Help Track How Parkinson’s Patients Respond to Treatment: Image: MIT neuroscientists imaged the substantia nigra in a young adult, left, an older adult, center, and a Parkinson’s patient, right. They found that the substantia nigra deteriorates in Parkinson’s patients (Photo courtesy of David Ziegler).

Panda sign: The panda sign in neuroimaging refers to the appearance of the midbrain, when the red nucleus and substantia nigra are surrounded by high T2 signal.(Click link for addl. images) It is classically seen in Wilson disease, although whenever the white matter is diffusely abnormal in the region a similar appearance will be perceived.
