Average beta burst duration profiles provide a signature of dynamical changes between the ON and OFF medication states in Parkinson’s disease

Average burst duration profiles can have complex shapes.
Thick lines highlight the duration of individual bursts for two thresholds in the left panel. The corresponding averages are identified with the same colour in the average burst duration profile in the right panel. Longer bursts are still present at the 80th percentile, and shorter bursts are significantly more frequent at the 70th percentile than at the 80th percentile. In addition, high amplitude, longer bursts are sharp (quick rise and fall), and therefore their duration is only shortened slightly from the 70th to the 80th percentile. As a result, the average burst duration profile is non-monotonic.
