- Description:
- Dopamine (DA) neurons are involved in many brain functions, and their dysfunction is associated with several neurodegenerative diseases. In recent years, our lab and others have found that DA neurons are molecularly diverse through single-cell gene expression profiling. An outstanding question in the field is whether this heterogeneity is encoded...
