Parkinson's disease is a complex neurodegenerative disorder that leads to the deterioration of specific types of neurons in the brain, resulting in a number of motor and non-motor symptoms.

In a new study in mice, a team of researchers from UCLA, the Swiss Federal Institute of Technology, and Harvard University have uncovered a crucial component for restoring functional activity after spinal cord injury. The neuroscientists have shown that re-growing specific neurons back to their natural target regions led to recovery, while random regrowth was not effective.

The hypothalamus, however, is a notable exception to this rule. ...
