JNP Micro Podcasts ”Four Questions”: Essential Tremor accentuates upper limb coherence patterns

In this podcast coauthor Daniel Free of Brigham Young University talks about the recently published article titled “Essential tremor accentuates the pattern of tremor-band coherence between upper limb muscles.”

 

NEW & NOTEWORTHY This research characterized the relationships in tremor-band activity between the 15 major superficial upper limb muscles of persons with essential tremor by quantifying the proportion of shared activity (coherence) in the tremor band and by characterizing phase differences between these muscles during various tasks. From the authors observations, they conclude that tremor enhances the coherence between muscle pairs throughout the upper limb in a pattern that reflects functional relationship between them.
