Spontaneous Events Drive Brain Functional Connectivity?

A new study claims that Functional Connectivity in MRI Is Driven by Spontaneous BOLD Events The researchers, Thomas Allan and colleagues from the University of Nottingham (one of the birthplaces of MRI), say that their results challenge the assumption that correlations in neural activity between 'networks' of brain regions reflect slow, steady low frequency oscillations within those networks. Instead, they report that the network connectivity is the result of occasional 'spikes' of coordinate
