Depressive and anxious phenotype correlates with functional changes in the ventromedial prefrontal cortex - dorsal raphe nucleus circuit in female mice with alpha-synucleinopathy
Parkinson’s disease (PD) is usually thought of as a motor disorder, although non-motor symptoms may precede the motor manifestations and are a key component of the PD. Among these, depression and anxiety are most prevalent symptoms and caused a greater symptomatic burden in women than in men. A dysfunctional serotonin (5-HT) system is generally considered a risk factor for depression. We propose the ventromedial prefrontal cortex (vmPFC)-dorsal raphe nucleus (DR) circuit as the key player underlying depressive/anxious disorders in PD, by virtue of its reciprocal connectivity. Female mice overe
