Our nervous system is one of the most complex systems in our body. It consists of billions of nerve cells that work in tandem and processes billions and billions of calculations per second. But how are these neurons formed in our body and what controls them? In a recent study, scientists have discovered a molecule that they claim controls the mechanism in which nerve cells are formed. This study may help uncover some of the key aspects that can treat neurodegenerative disorders like Parkinson’s.
