The Default Mode Network (DMN) is associated with
anti-correlation with task positive networks. In this
study, we investigate the DMNs response to spontaneous
motor events that are detected in the Somatosensory
Network. Sparse paradigm free mapping is used to detect
three movement types: long and short motor tasks, and
spontaneous movements without prior timing information.
DMN activity is compared for these three types. Results
indicate that the DMN has higher average of activation
for spontaneous events compared to task events. This
analysis can be further extended to explore the DMNs
behaviour for spontaneous events in other networks.
