Thalamic projections to the subthalamic nucleus contribute to movement initiation and rescue of parkinsonian symptoms.

Sci Adv 2021 Feb 5;7(6). Epub 2021 Feb 5.

Department of Psychology and Neuroscience, Duke University, Durham, NC 27708, USA.

The parafascicular nucleus (Pf) of the thalamus provides major projections to the basal ganglia, a set of subcortical nuclei involved in action initiation. Here, we show that Pf projections to the subthalamic nucleus (STN), but not to the striatum, are responsible for movement initiation. Because the STN is a major target of deep brain stimulation treatments for Parkinson's disease, we tested the effect of selective stimulation of Pf-STN projections in a mouse model of PD. Read More
