The brain is known to be segregated into relatively few large scale networks but it has been shown using fMRI that the brain has highly focal sub regions that respond to a specific task. During a task, whether it is externally or internally driven, multiple nodes of a network can be recruited to successfully complete the task. We investigate how spontaneous BOLD events, detected using paradigm free mapping, synchronise transiently and have specific plausible substructures within networks similar to fMRI studies by using temporal ICA.
