TL;DR

Understanding how diseases spread on brain networks can help predict and treat neurodegenerative diseases like Parkinson's.

Transcript

neurodegenerative diseases like Parkinson's are devastating illnesses that cause brain cells to die into brain to atrophy the hallmark symptom is movement disorders but there are actually a whole host of others such as disturbances and smell and sleep and memory impairments what we want to understand is how symptoms develop in individual subjects a...
