Stress-evoking emotional stimuli exaggerate deficits in motor function in Parkinson's disease.

abstract：:Working memory, the ability to maintain and manipulate information over seconds, is central to cognition and it is impaired in many clinical populations. However, our knowledge of the structural properties associated with individual variation in visuospatial working memory capacity is currently poor. Across two locati...
