New methods identify and manipulate 'newborn' cells in animal model of Parkinson's disease

When cells in the brain are lost through disease or injury, neighboring cells begin to divide and multiply, but only a few areas in the brain are able to produce new neurons. Patients with Parkinson's disease suffer degeneration of certain neurons that reside in an area of the brain called the substantia nigra and project into the striatum. Many of the newborn cells in these areas have not been well described because of limitations of methods used to characterize them.
