Researchers at the Fralin Biomedical Research Institute at VTC and the Virginia Tech College of Science have identified distinct brain signaling patterns that separate Parkinson’s disease (PD) from essential tremor (ET), two of the most common and often confused movement disorders. Published in Nature Communications , the study reveals that differences in serotonin signaling, not just dopamine signaling, may offer a new distinct signature to distinguish PD from essential tremor.

“This study builds on decades of work,” said so-senior Read Montague, PhD, director of the human neuroimaging lab and computational psychiatry unit at Fralin.

Co-senior author William “Matt” Howe, PhD, assistant professor with the School of Neuroscience in the Virginia Tech College of Science added: “What s
