Correcting for Non-stationarity in BOLD-fMRI Connectivity Analyses

Correcting for Non-stationarity in BOLD-fMRI Connectivity Analyses

In this work fMRI BOLD datasets are shown to contain slice-dependent non-stationarities. A model containing slice-dependent, non-stationary signal power is proposed to address time-varying signal power during BOLD data acquisition. The impact of non-stationary power on functional MRI connectivity is...
