Anxa1+ dopamine neuron vulnerability defines prodromal Parkinson's disease bradykinesia and procedural motor learning impairment
Progressive degeneration of dopamine neurons (DANs) defines Parkinson's disease (PD). However, the identity and function of the most vulnerable DAN populations in prodromal PD remain undefined. Here, ...
