Does function fit structure? A ground truth for non-invasive neuroimaging.

abstract：:Neuroimaging research has identified several brain systems sensitive to statistical regularities within environmental input. However, the continuous input impinging on sensory organs is rarely stationary and its degree of regularity may itself change over time. The goals of the current fMRI study were to identify syst...
