Retinotopic patterns of background connectivity between V1 and fronto-parietal cortex are modulated by task demands.

abstract：:Studying task modulations of brain connectivity using functional magnetic resonance imaging (fMRI) is critical to understand brain functions that support cognitive and affective processes. Existing methods such as psychophysiological interaction (PPI) and dynamic causal modeling (DCM) usually implicitly assume that th...
